Table of Contents

While writing a manuscript for the first time, you might find yourself confused about the differences between an abstract and the introduction. Both are adjacent sections of a research paper and share certain elements. However, they serve entirely different purposes. So, how does one ensure that these sections are written correctly?

Knowing the intended purpose of the abstract and the introduction is a good start!

What is an abstract?

An abstract is a very short summary of all the sections of your research paper—the introduction, objectives, materials and methods, results, and conclusion. It ends by emphasising the novelty or relevance of your study, or by posing questions for future research. The abstract should cover all important aspects of the study, so that the reader can quickly decide if the paper is of their interest or not.

In simple terms, just like a restaurant’s menu that provides an overview of all available dishes, an abstract gives the reader an idea of what the research paper has to offer. Most journals have a strict word limit for abstracts, which is usually 10% of the research paper.

What is the purpose of an abstract?

The abstract should ideally induce curiosity in the reader’s mind and contain strategic keywords. By generating curiosity and interest, an abstract can push readers to read the entire paper or buy it if it is behind a paywall. By using keywords strategically in the abstract, authors can improve the chances of their paper appearing in online searches.

What is an introduction?

The introduction is the first section in a research paper after the abstract, which describes in detail the background information that is necessary for the reader to understand the topic and aim of the study.

What is the purpose of an introduction?

The introduction points to specific gaps in knowledge and explains how the study addresses these gaps. It lists previous studies in a chronological order, complete with citations, to explain why the study was warranted.

A good introduction sets the context for your study and clearly distinguishes between the knowns and the unknowns in a research topic.

Often, the introduction mentions the materials and methods used in a study and outlines the hypotheses tested. Both the abstract and the introduction have this in common. So, what are the key differences between the two sections?

Key differences between an abstract and the introduction:

• The word limit for an abstract is usually 250 words or less. In contrast, the typical word limit for an introduction is 500 words or more.
• When writing the abstract, it is essential to use keywords to make the paper more visible to search engines. This is not a significant concern when writing the introduction.
• The abstract features a summary of the results and conclusions of your study, while the introduction does not. The abstract, unlike the introduction, may also suggest future directions for research.
• While a short review of previous research features in both the abstract and the introduction, it is more elaborate in the latter.
• All references to previous research in the introduction come with citations. The abstract does not mention specific studies, although it may briefly outline previous research.
• The abstract always comes before the introduction in a research paper.
• Every paper does not need an abstract. However, an introduction is an essential component of all research papers.

Abstract Vs. Introduction — Do you know the difference?

Ross wants to publish his research. Feeling positive about his research outcomes, he begins to draft his manuscript. After completing the abstract, he proceeds to write the introduction. That’s when he pauses in confusion. Do the abstract and introduction mean the same? How is the content for both the sections different?

This is a dilemma faced by several young researchers while drafting their first manuscript. An  abstract  is similar to a summary except that it is more concise and direct. Whereas, the  introduction  section of your paper is more detailed. It states why you conducted your study, what you wanted to accomplish, and what is your hypothesis.

This blog will allow us to learn more about the difference between the abstract and the introduction.

What Is an Abstract for a Research Paper?

An abstract provides the reader with a clear description of your research study and its results without the reader having to read the entire paper. The details of a study, such as precise methods and measurements, are not necessarily mentioned in the abstract. The abstract is an important tool for researchers who must sift through hundreds of papers from their field of study.

The abstract  holds more significance  in articles without open access. Reading the abstract would give an idea of the articles, which would otherwise require monetary payment for access. In most cases, reviewers will read the abstract to decide whether to continue to review the paper, which is important for you.

Your abstract should begin with a background or objective to clearly state why the research was done, its importance to the field of study, and any previous roadblocks encountered. It should include a very concise version of your methods, results, and conclusions but no references. It must be brief while still providing enough information so that the reader need not read the full article. Most journals ask that the abstract be no more than 200–250 words long.

Format of an Abstract

There are two general   formats — structured and unstructured. A  structured abstract   helps the reader find pertinent information  very quickly. It is divided into sections clearly defined by headings as follows:

• Background : Latest information on the topic; key phrases that pique interest (e.g., “…the role of this enzyme has never been clearly understood”).
• Objective : The research goals; what the study examined and why.
• Methods : Brief description of the study (e.g., retrospective study).
• Results : Findings and observations.
• Conclusions : Were these results expected? Whether more research is needed or not?

Authors get tempted to write too much  in an abstract but it is helpful to remember that there is usually a maximum word count. The main point is to relay the important aspects of the study without sharing too many details so that the readers do not have to go through the entire manuscript text for finding more information.

The  unstructured abstract  is often used in fields of study that do not fall under the category of science. This type of abstracts does not have different sections. It summarizes the manuscript’s objectives, methods, etc., in one paragraph.

Lastly, you must check the author guidelines of the target journal. It will describe the format required and the maximum word count of your abstract.

What Is an Introduction?

Your introduction is the first section of your research paper . It is not a repetition of the abstract. It does not provide data about methods, results, or conclusions. However, it  provides more in-depth information  on the background of the subject matter. It also explains your hypothesis , what you attempted to discover, or issues that you wanted to resolve. The introduction will also explain if and why your study is new in the subject field and why it is important.

It is often a good idea to wait until the rest of the paper is completed before drafting your introduction. This will help you to stay focused on the manuscript’s important points. The introduction, unlike the abstract, should contain citations to references. The information will help guide your readers through the rest of your document. The key tips for writing an effective introduction :

• Beginning:  The importance of the study.
• Tone/Tense:  Formal, impersonal; present tense.
• Content:  Brief description of manuscript but without results and conclusions.
• Length:  Generally up to four paragraphs. May vary slightly with journal guidelines.

Once you are sure that possible doubts on the difference between the abstract and introduction are clear, review and submit your manuscript.

Difference Between Abstract and Introduction

On the other hand, the abstract is like a short summary of an academic article or research paper, which discusses the purpose of the study and the outcome of the research. It usually summarizes the research topic, questions, participants, methods, outcome, data collected, analysis and conclusions. The article excerpt given hereunder discusses the difference between abstract and introduction.

Content: Abstract Vs Introduction

Comparison chart.

Definition of Abstract

An abstract can be described as a concise summary, often found in research work like thesis, dissertations, research articles, review, etc. which helps the reader to have an instant idea of the main purpose of the work. It is about a paragraph long of 150 to 250 words in general.

The information contained in the abstract should be sufficient enough to help the readers judge the nature and importance of the topic, the reasonableness of the strategy used in the investigation, nature of results and conclusions.

An abstract serves a number of purposes such as it allows the readers to get the gist of your paper, so as to decide whether to go through with the rest of the work. It is usually written after the writing of the paperwork is over and that too in the past tense.

An abstract rolls all the important information of the work into a single page, such as the context, general topic, central questions, problem under study, main idea, previous research findings, reasons, research methodology, findings, results, arguments, implications, conclusion and so on. To create an abstract one should pick the main statements from the above-mentioned sections, to draft an abstract.

Types of Abstract

• Descriptive Abstract : It briefly describes the abstract and the length is usually 100-200 words. It indicates the type of information contained in the paper, discusses the purpose of writing, objectives and methods used for research.
• Informative Abstract : As the name suggests, it is a detailed abstract which summarizes all the important points of the study. It includes results and conclusions, along with the purpose, objective, and methods used.

Definition of Introduction

Introduction means to present something to the readers, i.e. by giving a brief description or background information of the document. It is the first and foremost section which expresses the purpose, scope and goals, concerning the topic under study. As an introduction gives an overview of the topic, it develops an understanding of the main text.

An introduction is a gateway to the topic, as it is something which can create interest in the readers to read the document further. It is the crux of the document, which states what is to be discussed in the main body.

Elements of Introduction

An introduction has four basic elements namely: hook, background information, connect and thesis statement.

• Hook is the preliminary sentence of the introduction which is used to fasten the attention of the readers, and so it has to be interesting, attention-grabbing, and readable of course, so as to stimulate the readers to read the complete text.
• Background Information is the main part of the introduction, which presents the background of the research topic, including the problem under study, real-world situation, research questions, and a sneak peek of what the readers can expect from the main body.
• Connect , is a simple line which is used to link or say relate the background information with the research statement, by using words ideas or phrases, so as to ensure the flow and logic of writing the text.
• Thesis statement is the central point of the argument, which is usually a single sentence, whose points of evidence are to be talked about in the following text, i.e. the main body.

Key Differences Between Abstract and Introduction

The difference between abstract and introduction are discussed in the points:

• An abstract is a concise and accurate representation which gives an overview of the main points from the entire document. On the other hand, Introduction is the first section which makes the reader aware of the subject, by giving a brief description of the work, i.e. why the research is needed or important.
• While an abstract will give you an immediate overview of the paper, the introduction is the initial exposure to the subject under study.
• An abstract reports key points of the research, as well as it states why the work is important, what was the main purpose of research, what is the motivation behind choosing the subject, what you learned from the research, what you found out during the research and what you concluded, in a summarized way. As against, an introduction presents a direction to understand what exists in the upcoming portion of the document or book.
• As an abstract has its own introduction, main body and conclusion, it is a standalone document which summarizes the result of the findings and not just the list of topics discussed. As against, the introduction is not a standalone document or piece.
• The main purpose of an abstract is to provide a succinct summary of the research. Conversely, introduction aims at convincing the reader about the need for the research.
• An abstract contains the purpose, problem, methods used, result and conclusion. On the contrary, the introduction includes a hook, background information, connect and thesis statement.
• While abstract is found in a research paper, thesis and dissertations, the introduction is found in a wide range of texts.

An abstract gives a preview of the work, outlines the main points and helps the audience in decision making, i.e. whether they want to read the complete text or not. On the other hand, an introduction is the very first section of the work, which clarifies the purpose of writing.

Without an abstract and introduction, the readers might not be able to know what the work contains and what is the reason or motivation behind the research. So, these two are like thread which goes through the writing and creates an understanding in the reader about the topic under study. While writing these two, one should ensure that they accurately reflect what you cover in the document or book.

Abstract vs Introduction – Differences Explained

• By Dr Harry Hothi
• August 29, 2020

Any academic write up of a research study or project will require the inclusion of an abstract and introduction. If you pick up any example of a research paper for a journal, dissertation for a Masters degree or a PhD thesis, you’ll see the abstract, followed by the introduction. At first glance you’ll notice that the abstract is much shorter in length, typically a quarter or third of a page of A4. The introduction on the other hand is longer, taking up at least an entire page of writing.

Beyond the length, what are the differences in the content of the two sections? In short, the abstract is a summary of the entire study, describing the context, research aim, methods, results and key conclusions. The introduction gives more detail on the background of the subject area, the motivation for the study and states the aims and objectives.

Read on to learn more.

What is an Abstract?

The main purpose of an abstract is to succinctly give the reader an overview of why the study was needed, what the purpose of the project was, the research question, the key materials and methods that were used, the main results and what conclusions were drawn from this. Many abstracts also conclude with a sentence on the significance or impact of the research. These are sometimes also referred to as an executive summary.

The reader should have an understanding of the paper topic and what the study was about from the abstract alone. He or she can then decide if they want to read the paper or thesis in more detail.

Abstracts are particularly useful for researchers performing a literature review, which involves critically evaluating a large number of papers. Reading the abstract enables them to quickly ascertain the key points of a paper, helping them identify which ones to read in full.

Abstracts are also very important for learning more about the work performed in papers that are hidden behind academic journal paywalls (i.e. those that are not open access). Abstracts are always made freely available, allowing a researcher to understand the context and main point of the work and then decide if it’s worth paying to read the entire paper. These are sometimes referred to as the ‘de facto introduction’ to the research work as it’s usually the first section people read about your study, after the title page.

How do you Write an Abstract?

The majority of academic journals place a limit of 250 words on the length of the abstract in papers submitted to them. They do this to ensure you give a quick overview of only the most important information from your study, helping the reader decide if they want to read the whole paper too. Make sure you double check the specific requirements of your target journal before you start writing.

Universities or other academic institutions often allow up to 500 words for an abstract written for a doctoral thesis.

Abstracts can be either structured or unstructured in the way they are formatted. A structured abstract contains separate headings to guide the reader through the study. Virtually all STEM journals will require this format be used for a researcharticle. The exact names used for each heading can differ but generally there are defined as:

• Background. This is also sometimes called the Introduction. This section should give an overview of what is currently known about the research topic and what the gap in knowledge is. The reader should understand the problem your research will address; i.e. what was your study needed. Don’t include any references or citations in the abstract.
• Aim and Objective. Give a brief explanation of what the study intended to achieve and state the research question or questions that you proposed. Some authors also include the hypothesis here too.
• Materials and Methods. Use the methods section to describe what you investigated, what the study design was and how you carried it out.
• Results. Give an overview of your key findings.
• Discussion and Conclusion. Some journals may ask for these two terms to be used as separated headings. These sections explain why you may have obtained the results that you did, what this means and what the significance or impact of this might be.

An informative abstract should provide a concise summary of all the important points in your research project, including what the central question relating to the subject matter was. Make it interesting to read too; this may be the difference between your abstract being accepted or rejected if you decide to submit it to an upcoming conference. Reviewers for large conferences often have to read hundreds of abstracts so make sure yours stands out by being easy to read and follow.

It’s less common that you’ll be asked to write an unstructured abstract. If you are, however, be aware that the key difference is that an unstructured abstract does not include separate headings. The flow of the abstract text should still follow the 5 points listed above but they should all be written within one long paragraph.

What is the Introduction?

The introduction section is the first main written work presented after the abstract in your paper manuscript or thesis. In a research paper, the introduction will be followed by a section on the materials and methods. In thesis writing, the introduction will be followed by the literature review .

The main aim of introduction writing is to give the reader more detail on the background information of the study. It should include a brief description of the key current knowledge that exists based on the work presented in previous literature and where the gaps in knowledge are. The introduction should convey why your research was needed in order to add new understanding to your subject area. Make sure that you reference all the publications that you refer to.

When writing an introduction for a scientific paper you should also include the aim of your study and the research objectives/questions. If relevant, also include your hypothesis or (null hypothesis).

How do you Structure the Introduction?

The general rule of thumb for a research paper is to use size 12 Times New Roman font, double spaced. Write four separate paragraphs which together are no longer than one page in length. Structure the four paragraphs as follows:

• Set the context of the research study, giving background information about the subject area.
• Describe what is currently know from previously published work and what is poorly understood – i.e. the research gap.
• Explain how addressing this gap in knowledge is important for your research field – i.e. why this study is needed.
• Give a broad overview of the aims, objectives and hypothesis of the study.

You should not describe the research method used in this section nor any results and conclusions.

You should be clear now on what the differences between an abstract vs introduction are. The best way to improve your academic writing skills for these are to read other examples from other  research articles and start writing!

Abstract vs. Introduction

What's the difference.

The abstract and introduction are both important sections of a research paper or academic article, but they serve different purposes. The abstract is a concise summary of the entire paper, providing an overview of the research question, methodology, results, and conclusions. It is typically written in a single paragraph and is meant to give readers a quick understanding of the study without having to read the entire paper. On the other hand, the introduction is the first section of the paper and is more detailed. It provides background information on the topic, explains the research problem or question, and outlines the objectives and significance of the study. The introduction sets the stage for the rest of the paper and helps readers understand the context and motivation behind the research.

Further Detail

Introduction.

The introduction is an essential part of any academic or research paper. It serves as the opening section that provides background information, context, and sets the stage for the reader to understand the purpose and significance of the study. The introduction typically includes a thesis statement or research question, outlines the objectives, and highlights the main points that will be discussed in the paper.

One of the primary functions of the introduction is to grab the reader's attention and create interest in the topic. It often begins with a hook or an engaging anecdote to captivate the reader's curiosity. The introduction also provides a brief overview of the existing literature and research related to the topic, highlighting the gaps or limitations that the current study aims to address.

Furthermore, the introduction serves as a roadmap for the rest of the paper, outlining the structure and organization of the subsequent sections. It helps the reader understand the logical flow of the arguments and the overall structure of the paper. The introduction is typically longer than the abstract and provides more detailed information about the research topic.

In summary, the introduction acts as a bridge between the reader and the research paper, providing necessary background information, context, and setting the stage for the study.

The abstract, on the other hand, is a concise summary of the entire research paper. It is usually placed at the beginning of the paper, before the introduction, and provides a brief overview of the study's objectives, methods, results, and conclusions. The abstract aims to give the reader a quick understanding of the research without having to read the entire paper.

Unlike the introduction, the abstract is typically limited to a specific word count or character limit, often ranging from 150 to 300 words. Due to its brevity, the abstract focuses on the most important aspects of the research, highlighting the key findings and their implications. It does not provide an extensive background or literature review like the introduction does.

The abstract is written in a concise and objective manner, using clear and precise language. It avoids unnecessary details, jargon, or technical terms that may confuse the reader. The abstract should be able to stand alone and provide a comprehensive summary of the research, enabling readers to decide whether the paper is relevant to their interests or research.

Overall, the abstract serves as a condensed version of the entire research paper, providing a snapshot of the study's purpose, methods, results, and conclusions. It is designed to give readers a quick overview of the research without delving into the specifics.

While both the abstract and introduction play crucial roles in a research paper, they differ in several key aspects. Let's explore the main differences between these two sections:

1. Length and Detail

The most apparent difference between the abstract and introduction is their length and level of detail. The introduction is typically longer and more detailed, providing a comprehensive background, literature review, and outlining the structure of the paper. It delves into the topic, providing context and setting the stage for the study. On the other hand, the abstract is much shorter and concise, summarizing the key aspects of the research without going into extensive details.

2. Placement

Another significant difference is their placement within the research paper. The introduction is usually the first section after the abstract, serving as the opening of the paper. It provides the necessary background information and context before diving into the main body of the research. In contrast, the abstract is placed at the beginning of the paper, before the introduction, to provide a quick overview of the entire study.

The content of the abstract and introduction also differs. The introduction focuses on providing a comprehensive understanding of the research topic, including the background, literature review, objectives, and main points of the study. It aims to engage the reader and create interest in the research. On the other hand, the abstract summarizes the entire research paper, highlighting the key aspects such as the objectives, methods, results, and conclusions. It aims to give readers a quick understanding of the research without going into extensive details.

4. Audience

The target audience for the abstract and introduction also varies. The abstract is primarily aimed at researchers, scholars, and professionals who want to quickly assess the relevance and significance of the research. It helps them decide whether to read the full paper or not. In contrast, the introduction caters to a broader audience, including those who may not have in-depth knowledge of the subject. It provides the necessary background and context to make the research accessible to a wider range of readers.

Lastly, the abstract and introduction serve different purposes. The introduction aims to provide a comprehensive overview of the research topic, establish the research gap, and present the objectives and main points of the study. It sets the stage for the reader to understand the significance and relevance of the research. On the other hand, the abstract serves as a condensed summary of the entire research paper, allowing readers to quickly grasp the main findings and conclusions without reading the full paper.

In conclusion, while the abstract and introduction are both important sections of a research paper, they serve different purposes and have distinct attributes. The introduction provides a comprehensive background, context, and structure of the research paper, engaging the reader and setting the stage for the study. On the other hand, the abstract offers a concise summary of the entire research, highlighting the key aspects and enabling readers to quickly assess the relevance and significance of the study. Understanding the differences between these sections is crucial for researchers and readers alike to navigate and comprehend research papers effectively.

Abstract vs. Introduction—What’s the Difference?

• 3-minute read
• 21st February 2022

If you’re a student who’s new to research papers or you’re preparing to write your dissertation , you might be wondering what the difference is between an abstract and an introduction.

Both serve important purposes in a research paper or journal article , but they shouldn’t be confused with each other. We’ve put together this guide to help you tell them apart.

What’s an Introduction?

In an academic context, an introduction is the first section of an essay or research paper. It should provide detailed background information about the study and its significance, as well as the researcher’s hypotheses and aims.

But the introduction shouldn’t discuss the study’s methods or results. There are separate sections for this later in the paper.

An introduction must correctly cite all sources used and should be about four paragraphs long, although the exact length depends on the topic and the style guide used.

What’s an Abstract?

While the introduction is the first section of a research paper, the abstract is a short summary of the entire paper. It should contain enough basic information to allow you to understand the content of the study without having to read the entire paper.

The abstract is especially important if the paper isn’t open access because it allows researchers to sift through many different studies before deciding which one to pay for.

Since the abstract contains only the essentials, it’s usually much shorter than an introduction and normally has a maximum word count of 200–300 words. It also doesn’t contain citations.

The exact layout of an abstract depends on whether it’s structured or unstructured. Unstructured abstracts are usually used in non-scientific disciplines, such as the arts and humanities, and usually consist of a single paragraph.

Structured abstracts, meanwhile, are the most common form of abstract used in scientific papers. They’re divided into different sections, each with its own heading. We’ll take a closer look at structured abstracts below.

Structuring an Abstract

A structured abstract contains concise information in a clear format with the following headings:

●  Background: Here you’ll find some relevant information about the topic being studied, such as why the study was necessary.

●  Objectives: This section is about the goals the researcher has for the study.

●  Methods: Here you’ll find a summary of how the study was conducted.

●  Results: Under this heading, the results of the study are presented.

●  Conclusions: The abstract ends with the researcher’s conclusions and how the study can inform future research.

Each of these sections, however, should contain less detail than the introduction or other sections of the main paper.

Abstract vs. Introduction: What’s the Difference?

Home » Writing the Manuscript » Abstract vs. Introduction: What’s the Difference?

The main difference between and abstract and an introduction is that the abstract is a brief summary of your entire study—the aim or objective, methods, results, and conclusions—usually in that order. It gives the highlights of your work, with only the briefest background information.

In contrast, the introduction includes only some elements of what is in an abstract. In the abstract, you will expend the fewest words possible on the aims or objective section that opens it, just enough to let your reader know your research question. In the introduction, you will expand on the trail of evidence that led you to asking your research question.

What is an abstract for a research paper?

In an abstract, you summarize your work and capture the reader’s attention with the most important details about your work. Usually, you must give this information in 250 words or fewer.

The contents of the abstract

In just a couple of sentences, you start by giving your readers the background and objectives or specific aims, in just a few sentences. You then will give a few important details about the study design, number of participants or animals, treatments or interventions, controls, and so on. Then you will give the reader the most important results from your study, and end with a conclusion that communicates the most significant takeaway from those results. The language of the abstract should be as clear as possible, even to a nonspecialist.

You can find more specific information and examples of what to include in your abstract here, in this post, “ How to write an abstract for a research paper .”

What is the introduction of a research paper?

The introduction to a research paper orients your reader to the context of your study. It gives the reader just enough background to understand why you’re doing the work. Many journals require authors to keep introductions quite brief, limiting them to only 500 words or fewer in some cases. Even if a journal does not limit the length of the introduction, you should still try to be as concise as possible.

In this part of your paper, you will give the reader the chain of evidence that led you to ask the central question or questions of your study. This part of your paper does not need to give every single detail or cite every study in the field. You need only to walk the reader through the evidence that leads to your own study question or hypothesis. Usually, you will being with a general statement and then funnel down from that to your specific research question. For more specific information about writing introductions, see the blog post, “ How to write a great introduction to a research paper .”

7 differences between an abstract and an introduction

1. An abstract will include results. An introduction will almost never include results. At most, depending on the journal, you might give a sentence generalizing your findings.

2. An abstract will offer a conclusion. An introduction will almost never give the reader the main takeaway from the study findings.

3. The abstract will give some details about the methods and study design. The introduction will offer only the briefest information, such as “Here, using mice” or “In this study of patients with breast cancer.” Any details, including numerical values, will be reserved for the materials and methods section of the paper.

4. The abstract will have only a brief background section, usually consisting of a sentence or two, at most. The introduction, in contrast, will unfold this background succinctly but more expansively, giving the reader the context for why you asked the research question you did and the trail of evidence that has led to the study you performed.

5. The language in an abstract will likely be more accessible to nonspecialists reading the paper. You should avoid jargon and abbreviations as much as possible, and try to communicate your information as briefly and clearly as possible. The introduction, on the other hand, can be offer more details of interest to people in your field, and using abbreviations is OK.

6. An abstract will almost never contain reference citations. An introduction almost always will.

7. An abstract will usually run 250 words or fewer. Although some journals limit introductions to no more than 500 words, in many journals, the introduction can be longer.

A very few highest profile journals have some submission options that use the abstract as the introduction to the paper. These journals usually call these submission categories “Letters” or “Short submissions.” In such cases, the abstract serves as the introduction to the paper and is given as a fully referenced paragraph that both introduces the work and summarizes the results and design. You will know if this special merging of the abstract and introduction is a requirement if you consult the author instructions of your target journal.

Intro Vs Abstract – Are They The Same?

Scholarly writing serves as a cornerstone for the dissemination of knowledge and the exploration of new ideas. Two crucial elements that play a pivotal role in framing the structure of academic papers are the introduction and abstract. While often used interchangeably, these components serve distinct purposes, each contributing to a scholarly work’s overall coherence and effectiveness.

Table of Contents

Understanding The Introduction

The introduction serves as the gateway to a scholarly work, setting the stage for what lies ahead. It is not merely a perfunctory beginning but a strategic piece that aims to engage readers, provide context, and establish the groundwork for the research to follow. The primary functions of an introduction can be delineated into several key aspects.

Contextualization

The introduction contextualizes the research by presenting the broader field of study. It provides a backdrop against which the specific research question or problem statement can be understood.

This involves reviewing relevant literature, highlighting gaps in existing knowledge, and justifying the need for the current study.

Statement Of The Problem Or Research Question

One of the critical elements of an introduction is the formulation of a clear and concise research question or problem statement. This sets the trajectory for the entire paper, guiding readers on what to expect and why the study is significant.

Objectives And Scope

The introduction outlines the objectives of the research and delineates the scope of the study. This helps readers understand the boundaries within which the research is conducted and what specific aspects will be addressed.

Hypotheses Or Research Hypothesis

In scientific research, the introduction may present hypotheses that the study aims to test. These hypotheses are formulated based on existing knowledge and are critical for guiding the research methodology and analysis.

Thesis Statement

In some academic disciplines, particularly in humanities and social sciences, the introduction may encapsulate the thesis statement —a concise summary of the main argument or position taken in the paper.

Understanding The Abstract

While the introduction sets the stage, the abstract serves as a concise summary that encapsulates the entire research paper. Positioned at the beginning of the paper, the abstract acts as a standalone piece, providing readers with a snapshot of the research without requiring them to delve into the full text. The abstract has its own distinct set of functions and characteristics.

Summary Of Key Elements

The abstract encapsulates the essential elements of the research, including the research question, methodology, key findings, and conclusions. It serves as a condensed version of the entire paper, offering readers a quick overview.

Conciseness And Clarity

Unlike the introduction, the abstract is highly condensed and should be succinct. It demands clarity and precision in conveying the main points of the research without unnecessary details.

A well-crafted abstract can stand alone, providing readers with a clear understanding of the study even if they choose not to read the full paper.

Keywords And Indexing

Abstracts often include keywords that are relevant to the research. These keywords are essential for indexing and categorizing the paper in databases, making it easier for researchers to locate relevant literature.

No Citations Or References

Unlike the introduction, the abstract typically does not include citations or references in APA or MLA to other works. It is a self-contained unit that focuses solely on summarizing the research conducted in the paper.

Structural Alignment

The abstract should mirror the structure of the paper, summarizing each section in a logical sequence. It typically includes brief statements about the introduction, methodology, results, and conclusion.

What Is The Difference Between Intro Vs Abstract

While the introduction and abstract share the common goal of providing readers with a roadmap to the research, they differ significantly in their depth, scope, and functions. Understanding these distinctions is crucial for crafting a well-rounded and impactful research paper.

While an abstract is a tightrope walker, restricted to a concise space, the introduction enjoys the freedom of expansiveness. It can stretch across paragraphs, weaving a tapestry of context and intrigue.

An abstract concentrates on the “what” and the “how” – highlighting the research question, methodology, and results. The introduction delves deeper, exploring the “why” – establishing the importance of your work and engaging the reader emotionally.

An abstract primarily caters to specialists and peer reviewers and needs technical accuracy and jargon. The introduction speaks to a broader audience, using accessible language and captivating storytelling to pique their interest.

An abstract follows a rigid format, typically outlining the research question, methodology, results, and conclusion. The introduction offers greater flexibility, allowing for creative storytelling and engaging transitions.

Depth Of Detail

The introduction provides a comprehensive overview of the background, context, and rationale for the study. It delves into existing literature, establishes the research question, and outlines the objectives. In contrast, the abstract is a condensed summary, offering a snapshot of the entire paper without the depth of detail found in the introduction.

Inclusion Of Citations

The introduction extensively cites relevant literature reviews to provide a foundation for the research. It establishes the scholarly context and justifies the study’s significance. On the other hand, the abstract typically avoids citations and focuses on presenting the research’s key elements without reference to external works.

Readability And Accessibility

The introduction is designed to be read sequentially, guiding readers from the general to the specific. It is an integral part of the paper’s narrative, contributing to the overall flow. In contrast, the abstract is a standalone piece that should be easily understandable on its own. It serves as a quick reference for researchers scanning multiple papers to determine their relevance.

Function Within The Paper

The introduction serves as a foundation for the entire paper, providing the necessary context for readers to understand the study’s purpose and significance.

It invites readers into the research narrative, guiding them through the subsequent sections. On the other hand, the abstract is a succinct summary that allows readers to quickly assess the paper’s content, methodology, and findings without delving into the full text.

The research paper we write have:

• Precision and Clarity
• Zero Plagiarism
• High-level Encryption
• Authentic Sources

Strategies For Crafting Effective Introductions And Abstracts

Crafting compelling introductions and abstracts is a skill that evolves with practice and a nuanced understanding of the research process. Here are some strategies to enhance the effectiveness of these key components:

Clarity And Precision

Both the introduction and abstract benefit from clarity and precision. Use clear language to convey ideas and avoid unnecessary jargon. Ensure that each sentence serves a specific purpose and contributes to the overall coherence of the text.

Engaging The Reader

The introduction should engage the reader from the outset. Consider using anecdotes, thought-provoking questions, or relevant statistics to capture attention. Create a narrative flow that seamlessly leads readers from the general context to the specific research question.

Conciseness In The Abstract

Given its condensed nature, the abstract requires a careful selection of words to convey maximum information in a limited space. Avoid unnecessary details and focus on presenting the core elements of the research. Aim for brevity without sacrificing clarity.

Both the introduction and abstract should align with the overall structure of the paper. Ensure that the abstract provides a coherent summary of each section, mirroring the paper’s organization. Similarly, the introduction should seamlessly transition into subsequent sections.

Highlighting Significance

Clearly articulate the significance of the research in both the introduction and abstract. Explain why the study is relevant, what gaps it addresses, and how

Proofreading And Editing

Thoroughly proofread and edited both the introduction and abstract to eliminate grammatical errors, typos, and inconsistencies. Pay attention to the overall flow of the text, ensuring that ideas are presented logically and coherently.

The difference between an abstract and an introduction.

Introductions and abstracts are two things that seem very similar, but are actually quite different. However, once you know the difference, they are easy to keep separate from each other.

An abstract is, at its most basic level, a summary. It outlines all of the important parts of your paper to the reader, so they can figure out if your paper is worth reading. This is why abstracts are important in the scientific field. They are a fast way for someone to analyze what is going to be said, and if that information is going to be beneficial for them.

An introduction provides the reader with detailed background information about a topic. This helps the reader make sense of what is going to be said later in the paper. If they do not understand the most basic parts of your topic, then they are not going to understand what you are trying to convey.

Now that you know the difference between the two, here is some advice for writing them:

The abstract is easiest to write last. By that point, you will have already written everything else, and you should know the important takeaways of your work. In the abstract, you should introduce your topic, discuss why you choose this topic, state your hypothesis, and reveal the results of your study. Remember, the abstract is like a summary. You should not go into a lot of detail here. Provide the reader with enough information that they can digest what you are saying. You will explain everything else in detail later in your paper. 

The introduction is one of the most important parts of your paper. However, introductions vary based on the genre of paper. For this blog post, introductions for scientific papers are going to be discussed because abstracts are a staple of scientific reports. An introduction for a scientific paper should explain the reasoning behind why you choose this experiment, provide background information about the topic, reference other studies done on similar topics, and state your hypothesis. You want to make sure your reader can understand what is going to be said later in the paper.

What is the difference between an abstract and an introduction? This is a question that plagues many academic writers. In order to understand the difference, one should first understand the purpose each element plays in academic writing.

Abstracts in academic writing are intended for publication. Once the work has been published, the abstract acts as a summary for the reader so that the reader can determine if they want to take the time to read more of the work. When choosing a fiction novel, readers skim the back cover. When selecting research, they skim the abstract. When readers access the abstract, they are primarily thinking, “What can I learn from this study? Does it relate to my work?" Therefore, the reader is looking for a ​clear and concise summary of the document. When writing an abstract, common topics may include background, objective, methods, results, or conclusions.

Keep in mind that for student papers, APA 7th edition formatting does not actually require an abstract (see S​ection 2.9 of the APA Manual) since the overall purpose is designed for publication. However, it is not uncommon for instructors to require their students to include an abstract in their assignments. Oftentimes, this is because the instructor is preparing their students for writing their dissertation or thesis. Check your assignment or course syllabus to ensure you are meeting the requirements of your instructor.

Introductions

​​An introduction, on the other hand, is not a complete summary of document. Its primary purpose is to get the reader's attention by providing more details on the background of the topic and promote its relevance and significance. Here, the author also provides a  brief  overview of the content.

Abstract vs Introduction: What are the Key Differences?

Discover the key differences between abstracts and introductions in research papers, highlighting their roles, structures, and significance for compelling writing.

Jun 19, 2024

Abstract vs Introduction: What Are the Key Differences?

Writing a scientific paper involves several critical components, each serving a distinct purpose. Among these, the abstract and the introduction stand out as two of the most essential sections. Understanding the differences between these components is crucial for crafting a compelling and well-structured research paper. This article delves into the key differences between an abstract and an introduction, emphasizing their roles, structure, and significance.

Understanding Research Paper Components

A research paper is a detailed document presenting the findings of a study. It typically includes several sections: the title page, abstract, introduction, methods, results, discussion, and conclusion. Each section serves a unique purpose, guiding the reader through the research process and findings.

The abstract and the introduction are pivotal in setting the stage for the entire paper, drawing readers in, and providing a framework for understanding the research study.

Defining the Abstract: A Concise Summary of the Entire Paper

The abstract is a very short summary of the entire research paper , covering all sections, including the introduction, objectives, materials and methods, results, and conclusion. It should encapsulate all important aspects of the study, allowing readers to quickly determine if the paper is of interest.

Most journals impose a strict word limit for abstracts, often around 10% of the research paper’s length. This succinct summary serves as a gateway to the whole paper.

Key Elements of an Abstract

• Concise Summary: Provides a brief overview of the entire paper.
• Coverage: Includes all sections of the paper—introduction, methods, results, and conclusions.
• Word Limit: Typically constrained to a few hundred words, necessitating brevity and precision.
• Purpose: Enables readers to quickly decide whether to read the full paper.

Defining the Introduction: Setting the Stage for the Research Paper

The introduction is the first section in a research paper after the abstract. It is important to note that the introduction should not include a detailed description of the research method, which is reserved for the methods section. It describes the background information necessary for the reader to understand the topic and aim of the study.

The introduction provides more in-depth information on the background of the subject matter, explaining the hypothesis, what was attempted to discover, and issues that were resolved. This section sets the context for the entire study, explaining the significance of the research.

Key Elements of an Introduction

• Background Information: Offers context and explains the significance of the research topic.
• Research Objectives: States the aims and objectives of the study.
• Previous Research: Cites existing literature to justify the study.
• Hypothesis: Presents the research question and hypothesis.

The Role of Previous Research

Incorporating previous research effectively is crucial in both the abstract and the introduction. The introduction should include a brief description of the key current knowledge based on previous literature and where the gaps in knowledge are.

Citing previous research helps to explain why the study was warranted and provides context for the research topic. This literature review component is essential for grounding the research in existing scholarship.

Key Differences Between Abstracts and Introductions

Abstract: a standalone summary of key findings.

The abstract is a concise summary of the entire study , describing the context, research aim, methods, results, and key conclusions. Its main purpose is to give the reader an overview of the study, including the research question, methods, results, and conclusions.

It serves as a standalone summary, allowing readers to understand the essence of the research without reading the full paper. This structured abstract is critical for busy readers who need to quickly determine the relevance of a paper.

Introduction: Providing Context and Background for the Research

The introduction gives more detail on the background of the subject area, the motivation for the study, and states the aims and objectives. It conveys why the research was needed to add new understanding to the subject area. Unlike the abstract, the introduction does not summarize the entire study but sets the stage for the detailed discussion that follows.

This section is more expansive and uses past tense to describe what has been done and present tense for the research question and objectives.

Writing Effective Openers

Crafting a Compelling Abstract: Best Practices and Tips

• Identify the Abstract Type: Determine whether the abstract is descriptive or informative.
• Follow the Five-Section Structure: Include background, methodology, results, discussion, and conclusion.
• Adhere to Journal Guidelines: Follow word count and formatting requirements.
• Write from Scratch: Avoid redundancy and include crucial keywords.

A compelling abstract should be a succinct summary that highlights the most important aspects of the study, adhering to the abstract format required by the target journal.

Writing a Strong Introduction: Answering Key Questions and Setting the Tone

• Start with a Broad Overview: Highlight the research area and established knowledge.
• Identify Knowledge Gaps: Explain why these gaps need to be addressed.
• Present Research Objectives: State the research objectives and hypothesis clearly.
• Use Clear and Concise Language: Employ active voice and strong verbs to maintain clarity.

A good introduction sets a solid foundation for the research study, outlining the central question and providing a comprehensive background to engage the reader.

Best Practices and Common Mistakes

Using the abstract and introduction to guide the reader.

The abstract and introduction should work together to provide a clear understanding of the research study. The abstract should generate curiosity and contain strategic keywords, while the introduction provides the necessary background and context. This tandem ensures that readers are well-prepared to delve deeper into the research work.

Avoiding Common Mistakes in Abstract and Introduction Writing

• Avoid Redundancy : Do not copy text from the paper. Include only crucial keywords.
• Ensure Clarity: The abstract should be clear, comprehensive, and engaging.
• Accurate Introduction: Write the introduction after completing other sections to ensure accuracy and effectiveness.

Mastering the Abstract and Introduction for a Research Paper

Understanding the purposes, structures, and requirements of the abstract and introduction is essential for effective academic writing . The abstract provides a quick overview of the entire document, while the introduction sets the context and highlights the significance of the research study. Mastering these two sections is fundamental to engaging the audience and encouraging them to read the full paper.

By adhering to best practices and avoiding common pitfalls, researchers can craft compelling abstracts and introductions that effectively communicate their work’s significance and invite further reading.

The key difference between an abstract and an introduction lies in their function and scope: the abstract is a standalone summary, while the introduction provides detailed background information and sets the stage for the research.

Enhancing the Research Paper with a Good Abstract and Introduction

A well-written abstract and introduction are crucial for the success of a research paper. They not only capture the reader's attention but also provide a framework for understanding the entire study. These sections should be crafted with care, ensuring they are clear, concise, and informative.

More Detail on Writing Abstracts and Introductions

Abstracts: balancing brevity and comprehensiveness.

The abstract must balance brevity and comprehensiveness, providing a snapshot of the entire study without overwhelming the reader with details. It should highlight the main point and results expected, using a structured format to ensure all critical elements are covered. Whether it is a structured or unstructured abstract, the goal remains the same: to provide a quick overview of the research.

Introductions: Building a Strong Foundation

The introduction section should build a strong foundation for the paper, starting with a broad overview of the research topic and gradually narrowing down to the specific research question. It should include a brief description of previous studies and highlight the research problem. This section is typically written in the present tense, except when referring to past research.

Practical Tips for Writing Abstracts and Introductions

• Abstracts: Use the executive summary approach , ensuring all critical points are covered within the word limit.
• Introductions: Provide more detail on the background knowledge and context, ensuring the reader understands the importance of the research.
• Avoid Long Paragraphs: Keep paragraphs short and focused to maintain clarity and engagement.
• Adhere to Guidelines: Follow the specific requirements of the target journal or academic institution .

The Impact of a Well-Written Abstract and Introduction

A well-written abstract and introduction can significantly impact the reception of a research paper. They help to clearly communicate the research objectives, methods, and findings, making it easier for readers to quickly determine the relevance and importance of the study. These sections are critical for thesis writing, where the introduction sets the stage for the research, and the abstract provides a succinct summary.

Summary: Abstract vs Introduction in Research Papers

In summary, the key differences between an abstract and an introduction in a research paper are rooted in their purpose and scope.

The abstract is a very short summary that provides a quick overview of the entire study, while the introduction sets the stage by providing background information, stating the research objectives, and citing previous research. Both sections are essential for guiding the reader through the research paper and ensuring a clear understanding of the study’s significance.

By mastering the art of writing compelling abstracts and introductions, researchers can enhance the clarity and impact of their work, making it more accessible and engaging for a broad audience.

Abstract vs. Introduction: What is the actual difference?

Published on 07 Dec 2022

If you’ve never written a research paper, the number of boxes to check to complete it can be intimidating. Even if it’s not your first rodeo, there’s still so much to think about that it’s easy to get confused. 

The difference between an abstract and an introduction is a common concern for first-time research writers. 

While these parts may seem similar at first glance, they have distinct characteristics. Whether you’re writing a paper to submit to a journal, an academic conference , or for your MSc or PhD, crafting a good abstract and a unique introduction will save you hassle in the revision stages and increase the likelihood of your paper being accepted. 

What is the Difference Between an Abstract and an Introduction?

In around 250 words, an abstract summarizes the entire study and generates reader interest in your paper. An introduction is the first section of your paper. It covers background information, sets the context for your research, and is longer than an abstract (500 words or more).

The key difference between an abstract and an introduction is their purpose: 

• An abstract is an advertisement. 
• An introduction is a hook.

If you think of an abstract as an advertisement, it should be brief and summarize your paper entirely. People will have to spend their time (maybe even their money) reading your paper. So, your abstract should give them an initial idea of why your paper is relevant to them and what they can expect to learn.

Alternatively, thinking of your introduction as a “hook” means it’s the key to holding the long-term attention of a reader (once they’ve chosen to read your paper). An introduction isn’t about giving all of the research details, it’s about setting the scene for why the details matter.

Beyond purpose, the table below outlines the differences between abstracts and introductions:

How to Write a Good Abstract

Your abstract is likely the first thing people will read. It’s a particularly important tool for researchers that have to sort through piles of potential papers to review. 

So, make it clear what your paper is about, why that topic is important, and what you found in your research. Here are 3 tips for writing a good abstract…

1. Consider your abstract format 

There are two basic formats for abstracts. Often, the journal or program you are submitting to will outline what style they expect: 

• A structured abstract includes section headings.
• An unstructured abstract is a single block of text.

Regardless of this structural difference, both of these formats focus on answering the same set of key questions for prospective readers:

• Context/Background: Why is this topic and this research important?
• Objective: What questions are you trying to answer in your research?
• Methods/Design: What are the basic details of your research? In general, how did you go about answering the research questions? 
• Results: What answers did you find? Were there any other observations?
• Conclusion/Takeaways: Were your results expected? Is more research needed?

2. Keep your abstract clear and concise

Your abstract should efficiently deliver information in a way that non-specialists can understand. Detailed descriptions and scientific slang terms don’t belong here. Also, check specific author guidelines to know if there’s a word limit for your abstract (250 words is a common limit).

3. Beat writer’s block by outlining your paper

Just because your abstract is the first thing people will read doesn’t mean it’s the first thing you have to write. It’s helpful to have an outline or loose draft of your entire paper before you write your abstract . Highlight the most important points in each section, then use them to help frame your abstract.

How to Write a Good Introduction

After people have decided to read your paper, it’s your introduction’s time to shine. A good introduction sets the tone for the reader. 

So, make sure that your introduction gives context to your research and makes it clear why your reader should care. Here are 3 tips for writing a great introduction…

1. Answer these questions in your introduction

Some content in your introduction may overlap with your abstract. But, your introduction should cover key questions slightly differently (and in more detail) than your abstract:

• Why is your field of research important?
• What background information is needed to understand your research (include references where applicable)?
• What earlier research impacts the context of your own or helps with understanding your research process?
• How is your research innovative or original?
• What are the sections included in the rest of the paper?

2. Don’t save your introduction for last

“Save your intro for last” is a common tip for various writing applications. But it doesn’t need to be a rule. As Rachael Cayley outlines in this blog post : “You don’t always have to wait until the end to write your introduction. You should review it again of course, but since it's the setup [for the rest of your paper], it’s worth writing first.” 

The introduction shows your reader what led to your research question. So, writing or outlining that part of the story early (and before you forget the details) can help provide accurate context.

3. Consider your introduction’s tone and tense

Use a formal, impersonal tone and speak primarily in the present tense. Double-check the tense used in each sentence or example since there’s a chance you’ll talk about past research in contrast with new processes. Avoid using emotional appeals as they are more suitable for conference presentations and public speaking.

FAQ: Top Abstract and Introduction Questions

Can i use my abstract as my introduction.

The short answer to this question: You shouldn’t. Unless the journal (or your research advisor) asks you to merge your abstract and introduction, it’s best to keep them unique.

Structuring Your Research Paper: Knowing the difference between abstract, introduction, and conclusion

By charlesworth author services.

• 18 October, 2023

Research papers serve as essential tools in the dissemination of knowledge and the advancement of academic disciplines. Academic papers follow a well-defined structure and format that assists readers in comprehending the content efficiently. They adhere to a well-defined structure and format, which is often referred to as IMRaD: Introduction, Methodology, Results, and Discussion. In addition to these core elements, there are three crucial components; the Abstract, Introduction, and Conclusion, which enhance the deliverance of your research rationale and findings. Understanding the nuanced functions of these sections is crucial for researchers seeking to enhance their paper's clarity, engagement, and influence in the academic and scientific community.

These three components play distinct roles in the structure and communication of a written work, be it a research paper, a thesis, a report, or an article. To write effectively, it's essential to grasp the unique functions and structure of each.

What is an Introduction?

The introduction serves as the opening of your written work, where you set the stage for what is to come. It helps to make the first impression on your readers. Its primary purpose is to provide readers with an overview of the subject matter and the context in which your work exists. 

Furthermore, a well-written introduction outlines the research problem and introduces the main thesis or argument. Some journals may refer to this section as 'Background,' and in others, it might not have a separate heading.

Key elements of an introduction include:

1. Opening Sentence: A compelling hook or opening sentence that grabs the reader's attention and motivates them to continue reading.

2. Thesis Statement: A concise thesis statement that outlines the main argument, purpose, or objective of your work.

3. Background Information: Necessary background information or context to help readers understand the topic.

4. Scope and Significance: A brief discussion of what will be covered and why it is relevant or important.

An introduction should be clear, engaging, and give readers a sense of what to expect. While it provides some insight into the content, it does not delve into the details or findings of the work.

What is an Abstract?

The abstract is a concise summary of the entire document. Its primary purpose is to give readers a quick overview of the key points, methods, findings, and conclusions of the work. They are typically found at the beginning of research papers and articles and are often used by readers to determine whether they want to read the full text. It serves as a preview of the work and helps readers quickly gauge its relevance.

Key elements of an abstract include:

1. Objective: A clear statement of the research objective or purpose.

2. Methods: A brief description of the research methods or approach used.

3. Results: Summary of the key findings or results.

4.  Conclusions: A concise statement of the main conclusions or implications.

These elements are usually presented in a standalone paragraph or a few paragraphs, depending on the specific journal's guidelines.

The length of an abstract varies, often ranging from 150 to 250 words, though it can be longer for some longer papers or theses. Furthermore, it also depends on the style and guidelines of the publication.

What is a Conclusion?

The conclusion, as the name suggests, marks the end of your written work. Its primary purpose is to summarize and reiterate the main points and findings discussed in the body of the text. 

Key elements of a conclusion include:

1. Restatement of Thesis: A restatement of the main thesis or argument.

2. Summary of Findings: A brief summary of the key findings and results.

3. Implications: Discussion of the implications of the findings and their significance.

4. Closing Thoughts: A final thought or reflection on the subject matter.

The conclusion is the final part of the paper, summarizing the key findings, their implications, and the main takeaways. In some formats, this section follows the 'Discussion' and may not have a distinct heading.

The conclusion should leave the reader with a sense of closure and a clear understanding of the key takeaways. It is not the place to introduce new information or ideas but rather to reinforce the ideas presented in the body of the work.

What’s the Difference Between Abstract, Introduction, and Conclusion?

To better understand the distinctions and relationships between these three sections, here is a table comparing the features or characteristics of the abstract, introduction, and conclusion for your better understanding:

While these sections serve different functions, it's crucial to avoid repeating the same information. The abstract provides an overview, the introduction sets the stage, and the conclusion wraps up the key points. Repetition can bore readers and waste valuable space. Make each section unique and tailored to its purpose.

The abstract, introduction, and conclusion are the pillars that support the structure and impact of research papers. Understanding their differences and functions is fundamental to effective academic writing. By delving into their relevance, we can uncover their true significance, ensuring that the message of our research reaches its intended audience with clarity and impact.

An Abstract or an Introduction — What’s the Difference?

Are you working on a paper or scholarly article? Need to know the difference between an abstract and an introduction? Here’s what you need to know. 

An abstract and an introduction are two different sections of a research paper, thesis, or dissertation. An abstract is a short summary of the entire piece, and it comes before the table of contents. An introduction is a full-length chapter, and often includes a layout of the rest of the piece.

Abstract vs. Introduction — Key Takeaways

An abstract.

• Can be very short — a basic abstract only needs four sentences.
• A summary of the entire work. 
• Used in scholarly, academic, or scientific papers and articles.
• Comes before the table of contents. The page is not numbered.

An Introduction

• Is a full-length chapter.
• Often includes a map or layout of the piece to come. 
• Found in papers, articles, books, essays, compendiums, and more.
• After the table of contents. Considered a part of the work itself.

An abstract is a brief summary of the entire paper, that provides a concise overview of the research question, methods, results, and conclusions. According to the Chicago Manual of Style, an abstract may be “as many as a few hundred words but often much shorter.” 

It should be able to stand alone as a summary of the paper, allowing readers to quickly determine whether the paper is relevant to their interests.

An Example Abstract Format

For those in the sciences, the American Medical Association says, “Abstracts should summarize the main point(s) of an article and include the objective, methods, results, and conclusions of a study.”

In the arts and humanities — my field — a basic abstract format includes four statements:

• They say/I say

Methodology

What do these all mean? Let’s dive in.

They Say/I say

This is where you position your research within the broader field of scholarship. For example: 

Many scholars believe that vampires don’t like sunshine (they say), but most aren’t considering all the vampires who do like sunshine (I say). Tweet

This is where you discuss the kind of research you did. For example:

Over the course of one year, I trekked across Transylvania looking at ancient records and interviewing contemporary vampires.

This is where you summarize the main argument (thesis) that your paper asserts. For example:

This paper reveals that 77% of vampires do in fact tolerate or even enjoy sunshine.

The takeaway answers the question, So what? This is where you make a case for the broader implications of your claim. For example:

By understanding the diurnal (daytime) nature of most vampires, we can renovate our understanding of their culture and begin to break down barriers between vampires and non-vampires.

Introductions

As opposed to an abstract, which comes before a paper, the introduction is the first section of the paper , which introduces the research question, provides background information on the topic, and outlines the purpose and objectives of the study. The introduction sets the stage for the research and helps readers understand why the research was conducted and what it hopes to achieve. I had a professor who used to say that the introduction “sets the table for the meal of the paper to come.”

Information from the abstract may appear in the introduction, but it will be expanded upon and more detailed. 

The Format of an Introduction

An introduction, unlike most abstracts, will contain multiple paragraphs. While the abstract comes before the table of contents, the introduction comes after, and, according to the Oxford Style guide and common academic practice, begins on page #1. 

An introduction will often include the following information:

• Opening Gambit — An anecdote, joke, personal narrative, etc. to ‘hook’ the reader.
• They Say/I say — Position your work in the broader field of study. This will be more fleshed out than in the abstract. 
• Thesis Statement — Your main argument.
• Methodology — An overview of the kind of research you conducted. (Note that the methodology comes after the thesis statement in an introduction, unlike in the abstract.)
• Map of the Paper — This is where you tell your reader what to expect from each section of the paper. “In chapter 1, I look at…” etc.
• Restate the Thesis — Restate your main argument.

As to the “map of the paper,” I should note that not everyone agrees on this — the Chicago Manual of Style advises against it. And yet, it is a common academic practice. When in doubt, always check with your teacher or publisher.

Abstracts and Introductions

The main difference between an abstract and an introduction is that an abstract is a brief summary of the entire paper which appears before the table of contents, while an introduction provides a more in-depth view of the research question, background information, and the purpose of the study. Unlike abstracts, many introductions include a map of the paper that follows.

Abstract vs Introduction: What Are The Differences?

by  Antony W

June 26, 2024

Writing a research paper can be challenging because you have to consider so many factors before you start to put words on the paper. You have to choose a research topic, go through the entire research process , create an outline, write your first draft, and proofread your work for coherence, factualness, and clarity.

One area many students don’t seem to get right is on the outline of the paper. Often, they struggle to see a visible difference between an abstract and an introduction, so much so that they confuse the two to mean the same thing. 

Before we go any further, it’s important to understand that an introduction and an abstract for a research paper are not synonymous. They’re different in length, context, writing approach, and the intended purpose.

In this guide, you’ll learn about abstract vs introduction to understand the differences between these two parts of a research paper . In the end, you should find it easy to write a more comprehensive research paper that your instructor will love to read.

Without further ado, let’s get to it.

What is an Abstract in a Research Paper?

An abstract is a section of a research project that gives a reader a condensed version of a research project. Written in past tense, the abstract shows why the study was necessary, the overall purpose of the project, the research question , the materials and methods used, and the drawn conclusions and results. In some cases, an abstract might include an executive summary, which is a conclusive sentence that demonstrates the significance of the research.

The overall goal of an abstract in a research paper is to give a reader the complete summary of the entire project. In fact, by reading this section alone, one should get a clear understanding of the topic and understand the significance of the study.

Abstract are particularly useful because they help with decision-making. After reading the abstract of your research paper, a reader can decide if they want to read the rest of the document for more insights.

What is an Introduction in a Research Paper?

An introduction is the first main section in a research paper. Written immediately after the abstract and before the literature review , the introduction is the part of the project that gives a reader more information on the topic under investigation.

By reading the introduction, a reader should easily understand the knowledge that already exists on the subject and clearly see why your research is necessary for the topic in question. Given that you’re trying to add new understanding to the subject, the aim of your study and research objectives should be very clear.

Where possible, and if indeed necessary, the introduction of the research paper should include a hypothesis . 

Abstract vs Introduction: How Do They Compare?

The comparison table below shows the side-by-side comparison between an abstract and an introduction in a research paper.

Explaining the Differences between an Abstract and an Introduction

There are at least three significant differences between an abstract and an introduction, and it’s important to learn about them before you start writing a research paper.

Abstract vs Introduction: Purpose

The purpose of an abstract is to give your reader a clear, concise summary of the study you conducted on a particular subject. Written in past tense, the abstract is the section that demonstrates whether the paper fits the needs of the reader enough to get them to read other section of the paper. So to grab their attention, pique their interest, and get them to want to continue reading, you should write the abstract in such a manner that it conveys what the paper is about and why it’s important.

An introduction, on the other hand, prepares your reader to discover what you did in your study. It’s in the introduction that you explain:

• Why your study on the subject is important
• Exactly what the study examines
• The studies already conducted in the field

The introduction should also give a summary of what you did in the study.

Abstract vs Introduction: Structure

An abstract doesn’t require the use of subheadings and it’s mostly one block of text. Still, you can structure the abstract such that the information you present flows in a given sequence. You may want to organize your information in the following order:

• The significance of your study
• The basics of your subject
• Questions you’re trying to answer
• How you arrived at your answer and
• The answer to the question

By including this information in their right sequence, you’ll not only be able to give a clear overview of the whole research paper but also give your readers the reasons to keep reading. 

The introduction, on the other hand, may have subheadings to better prepare your reader to understand the study. So you might want to have the following structure overall:

• The importance of the study
• Background information that provides readers with a clear roadmap for the study
• A touch on the previous research that have an impact on the study
• Reasons to investigate the topic even further
• What you intend to do in the study

Structuring your introduction in this manner makes it easy for your readers to care about the study.

Abstract vs Introduction: Length

Many journals require that an abstract be between 200 and 600 words long. For your research paper, you’ll have to make yours at most 350 words, which means you have to write a lot in a small space.

An introduction tends to be longer, often up to 2 pages double-spaced for a normal research article.

Difference Between an Abstract and an Introduction

Sarah is eager to publish her research article and, fueled by her positive results, she embarks on drafting her research. After successfully completing the abstract, she confidently moves on to tackle the introduction. However, she suddenly finds herself stumped by a perplexing question: Do the abstract and introduction serve the same purpose? And how do they differ from each other?

This predicament is a common hurdle faced by many aspiring researchers when writing their inaugural research articles. Although an abstract provides a concise summary of the main points and findings of a research paper or article, an introduction presents an overview of the topic, context, and objectives of the study, leading to the main content.

Welcome to this article where we explore the differences between an abstract and an introduction. In this piece, we will dive into the different characteristics of these two sections in academic writing. Understanding the disparity between an abstract and an introduction is crucial for crafting well-structured research papers or articles. So, let’s delve into the specifics and unravel the differences between an abstract and an introduction!

Table of Contents

What is an Abstract?

An abstract is a concise summary of a research paper or article, providing an overview of the main objectives, methods, results, and conclusions. Its purpose is to give readers a quick snapshot of the entire work without delving into the details. Typically shorter in length, consisting of a paragraph or a few paragraphs, the abstract acts as a standalone summary that captures the essence of the research.

What is an Introduction?

The introduction plays a crucial role in setting the stage for the research. It introduces the topic, provides background information, and outlines the scope and purpose of the paper or article. Unlike the abstract, the introduction is longer, ranging from a few paragraphs to several pages. It establishes the context, discusses previous research, and introduces the specific objectives and structure of the work.

Purpose and Length

The purpose of an abstract is to provide a concise summary of the research, condensing the key points and conclusions into a brief overview. It aims to give readers a glimpse of the entire work in a succinct manner. Abstracts are often limited to a specific word count or character limit, commonly ranging from 150 to 300 words. In contrast, the introduction serves to engage readers, provide background information, and prepare them for the subsequent sections of the paper or article. It allows for a more detailed discussion of the topic, providing a comprehensive understanding for the reader. As a result, the length of an abstract is relatively shorter, while the introduction allows for more extensive content and exploration.

Content and Placement

An abstract focuses on summarizing the entire paper or article, highlighting the main objectives, methods, results, and conclusions . It provides a bird’s-eye view of the research, presenting the key findings without going into specific details. The abstract is usually placed at the beginning of the paper or article, before the introduction, to provide readers with a concise overview before they delve into the full text.

In contrast, the introduction aims to establish the context of the research. It discusses the significance of the topic, presents relevant background information , and sets the foundation for the study. The introduction introduces the research questions, objectives, and hypothesis , giving readers a clear understanding of the purpose and scope of the work. It is typically located at the beginning of the paper or article, after the abstract (if present), and serves as a bridge between the abstract and the main body of the text.

Readership and Tense

The abstract is often read by individuals who want a quick understanding of the research without going through the entire paper or article. It should be concise, informative, and engaging, capturing the attention of readers and providing them with the main points in a condensed form. When writing the abstract, the past tense is generally used since it summarizes the completed work.

In contrast, the introduction targets readers who are interested in gaining a comprehensive understanding of the topic and the research. It aims to engage their interest, provide relevant background information, and establish the rationale for the study. The present tense is usually employed in the introduction as it introduces the topic and provides current context and background information for the readers.

Details and Citation

An abstract does not typically include specific details or elaborate explanations. It presents a summary of the research without going into the nuances or intricacies. The abstract aims to give readers an overview of the research without overwhelming them with excessive details. In most cases, citations or references are not included in the abstract.

In contrast, the introduction allows for more detailed explanations, providing readers with the necessary background information and context for the study. It may include citations or references to relevant literature to support the claims and provide a foundation for the research. The introduction aims to give readers a comprehensive understanding of the topic and its significance, preparing them for the subsequent sections of the paper or article.

Here’s a table highlighting the key differences between an abstract and an introduction:

In summary, the abstract and the introduction serve distinct purposes in academic writing. While the abstract provides a concise summary of the entire research, the introduction sets the stage, introduces the topic, and establishes the context. Understanding the differences between these two sections is crucial for crafting well-structured and informative research papers or articles. By effectively utilizing both the abstract and the introduction, researchers can engage readers, provide a comprehensive overview of their work, and contribute to the advancement of knowledge in their respective fields.

Frequently Asked Questions (FAQs)

What information should be included in an abstract and an introduction.

An abstract should include a brief overview of the research problem, the research objectives, the methodology employed, the main findings or results, and the implications or significance of the study. In contrast, an introduction should provide background information on the topic, identify the research problem, state the research objectives and research questions, and outline the structure of the paper.

What is the length and placement of an abstract and an introduction?

The abstract is typically a standalone section placed at the beginning of a research paper and is usually limited to a specific word count or character limit, such as 150-300 words. The introduction follows the abstract and is a more extensive section that sets the stage for the research and is approximately 10-15% of the total length of the paper, usually ranging from 500-1000 words maximum.

Can an abstract be used as a substitute for an introduction?

No, an abstract cannot serve as a substitute for an introduction. While an abstract provides a summary of the entire paper, it lacks the comprehensive background information and contextualization that an introduction offers. The introduction provides the necessary foundation for readers to understand the significance and relevance of the research.

Are there any formatting differences between an abstract and an introduction?

In terms of formatting, an abstract is typically a single, concise paragraph that is often written in a structured format with subheadings such as Background, Objective, Methods, Results, and Conclusion. While, an introduction is more flexible and can be organized in multiple paragraphs, providing a narrative flow that introduces the topic gradually.

Is there a specific order in which the abstract and introduction should be written?

It is generally recommended to write the abstract and introduction after completing the main body of the research paper. This allows the author to have a clear understanding of the research findings and the overall structure of the paper, enabling them to summarize and introduce the content more effectively.

How to Write an Abstract | Steps & Examples

Published on February 28, 2019 by Shona McCombes . Revised on July 18, 2023 by Eoghan Ryan.

An abstract is a short summary of a longer work (such as a thesis ,  dissertation or research paper ). The abstract concisely reports the aims and outcomes of your research, so that readers know exactly what your paper is about.

Although the structure may vary slightly depending on your discipline, your abstract should describe the purpose of your work, the methods you’ve used, and the conclusions you’ve drawn.

One common way to structure your abstract is to use the IMRaD structure. This stands for:

• Introduction

Abstracts are usually around 100–300 words, but there’s often a strict word limit, so make sure to check the relevant requirements.

In a dissertation or thesis , include the abstract on a separate page, after the title page and acknowledgements but before the table of contents .

Hover over the different parts of the abstract to see how it is constructed.

This paper examines the role of silent movies as a mode of shared experience in the US during the early twentieth century. At this time, high immigration rates resulted in a significant percentage of non-English-speaking citizens. These immigrants faced numerous economic and social obstacles, including exclusion from public entertainment and modes of discourse (newspapers, theater, radio).

Incorporating evidence from reviews, personal correspondence, and diaries, this study demonstrates that silent films were an affordable and inclusive source of entertainment. It argues for the accessible economic and representational nature of early cinema. These concerns are particularly evident in the low price of admission and in the democratic nature of the actors’ exaggerated gestures, which allowed the plots and action to be easily grasped by a diverse audience despite language barriers.

Keywords: silent movies, immigration, public discourse, entertainment, early cinema, language barriers.

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

You will almost always have to include an abstract when:

• Completing a thesis or dissertation
• Submitting a research paper to an academic journal
• Writing a book or research proposal
• Applying for research grants

It’s easiest to write your abstract last, right before the proofreading stage, because it’s a summary of the work you’ve already done. Your abstract should:

• Be a self-contained text, not an excerpt from your paper
• Be fully understandable on its own
• Reflect the structure of your larger work

Start by clearly defining the purpose of your research. What practical or theoretical problem does the research respond to, or what research question did you aim to answer?

You can include some brief context on the social or academic relevance of your dissertation topic , but don’t go into detailed background information. If your abstract uses specialized terms that would be unfamiliar to the average academic reader or that have various different meanings, give a concise definition.

After identifying the problem, state the objective of your research. Use verbs like “investigate,” “test,” “analyze,” or “evaluate” to describe exactly what you set out to do.

This part of the abstract can be written in the present or past simple tense  but should never refer to the future, as the research is already complete.

• This study will investigate the relationship between coffee consumption and productivity.
• This study investigates the relationship between coffee consumption and productivity.

Next, indicate the research methods that you used to answer your question. This part should be a straightforward description of what you did in one or two sentences. It is usually written in the past simple tense, as it refers to completed actions.

• Structured interviews will be conducted with 25 participants.
• Structured interviews were conducted with 25 participants.

Don’t evaluate validity or obstacles here — the goal is not to give an account of the methodology’s strengths and weaknesses, but to give the reader a quick insight into the overall approach and procedures you used.

Don't submit your assignments before you do this

Next, summarize the main research results . This part of the abstract can be in the present or past simple tense.

• Our analysis has shown a strong correlation between coffee consumption and productivity.
• Our analysis shows a strong correlation between coffee consumption and productivity.
• Our analysis showed a strong correlation between coffee consumption and productivity.

Depending on how long and complex your research is, you may not be able to include all results here. Try to highlight only the most important findings that will allow the reader to understand your conclusions.

Finally, you should discuss the main conclusions of your research : what is your answer to the problem or question? The reader should finish with a clear understanding of the central point that your research has proved or argued. Conclusions are usually written in the present simple tense.

If there are important limitations to your research (for example, related to your sample size or methods), you should mention them briefly in the abstract. This allows the reader to accurately assess the credibility and generalizability of your research.

If your aim was to solve a practical problem, your discussion might include recommendations for implementation. If relevant, you can briefly make suggestions for further research.

If your paper will be published, you might have to add a list of keywords at the end of the abstract. These keywords should reference the most important elements of the research to help potential readers find your paper during their own literature searches.

Be aware that some publication manuals, such as APA Style , have specific formatting requirements for these keywords.

It can be a real challenge to condense your whole work into just a couple of hundred words, but the abstract will be the first (and sometimes only) part that people read, so it’s important to get it right. These strategies can help you get started.

Read other abstracts

The best way to learn the conventions of writing an abstract in your discipline is to read other people’s. You probably already read lots of journal article abstracts while conducting your literature review —try using them as a framework for structure and style.

You can also find lots of dissertation abstract examples in thesis and dissertation databases .

Reverse outline

Not all abstracts will contain precisely the same elements. For longer works, you can write your abstract through a process of reverse outlining.

For each chapter or section, list keywords and draft one to two sentences that summarize the central point or argument. This will give you a framework of your abstract’s structure. Next, revise the sentences to make connections and show how the argument develops.

Write clearly and concisely

A good abstract is short but impactful, so make sure every word counts. Each sentence should clearly communicate one main point.

To keep your abstract or summary short and clear:

• Avoid passive sentences: Passive constructions are often unnecessarily long. You can easily make them shorter and clearer by using the active voice.
• Avoid long sentences: Substitute longer expressions for concise expressions or single words (e.g., “In order to” for “To”).
• Avoid obscure jargon: The abstract should be understandable to readers who are not familiar with your topic.
• Avoid repetition and filler words: Replace nouns with pronouns when possible and eliminate unnecessary words.
• Avoid detailed descriptions: An abstract is not expected to provide detailed definitions, background information, or discussions of other scholars’ work. Instead, include this information in the body of your thesis or paper.

If you’re struggling to edit down to the required length, you can get help from expert editors with Scribbr’s professional proofreading services or use the paraphrasing tool .

Check your formatting

If you are writing a thesis or dissertation or submitting to a journal, there are often specific formatting requirements for the abstract—make sure to check the guidelines and format your work correctly. For APA research papers you can follow the APA abstract format .

Checklist: Abstract

The word count is within the required length, or a maximum of one page.

The abstract appears after the title page and acknowledgements and before the table of contents .

I have clearly stated my research problem and objectives.

I have briefly described my methodology .

I have summarized the most important results .

I have stated my main conclusions .

I have mentioned any important limitations and recommendations.

The abstract can be understood by someone without prior knowledge of the topic.

An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:

• To help potential readers determine the relevance of your paper for their own research.
• To communicate your key findings to those who don’t have time to read the whole paper.

Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarizes the contents of your paper.

An abstract for a thesis or dissertation is usually around 200–300 words. There’s often a strict word limit, so make sure to check your university’s requirements.

The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis , dissertation or research paper .

Avoid citing sources in your abstract . There are two reasons for this:

• The abstract should focus on your original research, not on the work of others.
• The abstract should be self-contained and fully understandable without reference to other sources.

There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.

The abstract appears on its own page in the thesis or dissertation , after the title page and acknowledgements but before the table of contents .

Abstract vs. Introduction: What’s the Difference?

The main difference between the abstract and introduction is that the abstract is a brief summary of the entire paper whereas the introduction is an opening statement that provides context and background information on the topic.

Before we move to more differences, let’s first understand Abstract and Introduction:

Differences between Abstracts and Introductions in APA

Understanding Abstracts

When submitting to a scholarly journal, you’ll definitely want to prepare an abstract. If the work’s end goal is assignment completion for a course, your professor’s requirement of including an abstract serves as a fantastic opportunity to develop the writing skills needed for publication. Abstracts are challenging to write and require practice because they’re so brief (under 250 words) and critical—they’re the hooks or “elevator speeches,” if you will, that are designed to draw readers to your research when source material is being perused. Abstract paragraphs should be rich in search terms that align with the main points of the overall work—this will also help guide traffic to your research if the published work is archived online.

Understanding Introductions

In an introduction, you establish the problem being studied and describe the context of your research. Unlike an abstract, a complete introduction may take a few pages, depending on the complexity of your work. There are several critical questions that need to be answered in an intro: What similar research does this work align with? How is this research furthering the conversation? What is the purpose of this study, and are there relevant theories that need to be introduced?

Here are some basics to become familiar with when developing abstracts and introductions…

• Choose active voice instead of passive
• Use present tense to discuss results and conclusions that are currently applicable
• Use past tense to discuss measured outcomes
• Stick to between 150 to 250 words (each journal will have its own limit)
• Avoid evaluating the paper’s contents

Introductions

• Move from the general to the specific, ending with a thesis
• Describe relevant research, in brief, and provide appropriate citations
• Explain the importance of the problem and need for research
• Write for a wide professional audience, not just specialists
• Avoid bias (especially when discussing controversy or conflicts)

Visually, the two sections will look very different on the page due to formatting requirements and varying lengths. It can be helpful to have a snapshot of how these sections look in a final document—check out pages 2 and 3 of the Purdue OWL’s APA sample paper . And, as always, if you have any questions as you draft your own abstracts and introductions, drop us a line: [email protected].

If you would like additional details straight from the source, consult The Publication Manual of the APA, 6 th edition , sections 2.04 (abstracts) and 2.05 (introductions).

Difference b/w Abstract and Introduction writing for a research paper

I was slightly confused with differentiating Abstract and Introduction writing for a research paper. What is the difference between these sections? They seem to be similar.

An abstract should cover the whole paper. It reports what the paper is for, what you did and the conclusion. E.g.

This paper explores the hypothesis that you can't teach an old dog new tricks. The experiment classifies new tricks as tricks the dog hasn't learned before. Six dogs were used in the trial. Three old, three not old. Two tricks were used. One the dogs knew and one the dogs did not. The results show that old dogs can learn new tricks.

The introduction should give the rationale for your paper. It will cite references to back up the reasoning behind your hypotheses, define what you mean, and explain what you hope to find out.

For centuries philosophers have posited that old dogs can't learn new tricks (Surname, 1788). However, it has been claimed that this stance is not backed up by scientific research (Smith, 1998; Jones, 2001) and is actually based on an old wives tale (Doe, 1967). Two issues arise from trying to accurately tell if old dogs can learn new tricks: what is an old dog and what is a new trick...

• 3 The end of the introduction also briefly describes each section of the paper. "In section 2 we describe and justify the methodology used. In section 3 we present the results we obtained. In section 4 we discuss the possible interpretations of the results. Lastly, in section 5 we conclude by wildly extrapolating our dog results to humans, and then we summarize for those too lazy to read the rest of the paper." –  dmm Commented Dec 19, 2014 at 15:42

The writing of the abstract and introduction of a paper is a very difficult task because if you have 1000 readers most of them read these parts and your paper evaluation strongly depends on these parts too.

In abstract, you should give an overall view of the paper including the importance and necessity of the paper topic (the first line of the abstract), the previous works and difficulties on this topic( second and third lines), the big picture of your novelty in this paper (fourth and fifth lines), and verifying your results (the final part of the abstract).

For Introduction, you should provide an extended abstract here. Write a paragraph to explain the ingredients of the abstract as I explained. The important fact in this part is to write everything with a valid reference for it. Also in the paragraph containing "the previous works and difficulties on this topic", you should carefully review and categorize the benchmark techniques in the topic of the paper and specify exactly the subtopic of your work. Also for your novelty and contribution, you should clearly state your approach with benefits versus the earlier works.

Also, you don't to refer works in the abstract (exception if your work is directly related to the earlier published works) but you should mention important and benchmark works on the paper topic in the introduction section.

Friendly speaking, you should mention the recent works in your introduction and also some published ones in the target publication for submitting!

To see good examples, you can see most published works on highly valued journals.

An abstract can be defined as a summary of the information in a document.

• It should not exceed 250 words
• It should be written in one paragraph.
• It should be written in the past tense as it refers to work done.
• Long words should be followed by its abbreviation which would be used through out the abstract and paper.
• It should not cite any references (except in rare cases)
• It should never give any information or conclusion that is not stated in the paper
• Must be accurate with respect to figures quoted in the main text.

Introduction

• It should present the nature and scope of the problem investigated
• Review the pertinent literature
• State the method of investigation
• State the principal results of the investigation
• State the principal conclusion(s) suggested by the results
