Research Questions vs Hypothesis: What’s The Difference?

by  Antony W

August 1, 2024

You’ll need to come up with a research question or a hypothesis to guide your next research project. But what is a hypothesis in the first place? What is the perfect definition for a research question? And, what’s the difference between the two?

In this guide to research questions vs hypothesis, we’ll look at the definition of each component and the difference between the two.

We’ll also look at when a research question and a hypothesis may be useful and provide you with some tips that you can use to come up with hypothesis and research questions that will suit your research topic . 

Let’s get to it.

What’s a Research Question?

We define a research question as the exact question you want to answer on a given topic or research project. Good research questions should be clear and easy to understand, allow for the collection of necessary data, and be specific and relevant to your field of study.

Research questions are part of heuristic research methods, where researchers use personal experiences and observations to understand a research subject. By using such approaches to explore the question, you should be able to provide an analytical justification of why and how you should respond to the question. 

While it’s common for researchers to focus on one question at a time, more complex topics may require two or more questions to cover in-depth.

When is a Research Question Useful? 

A research question may be useful when and if: 

• There isn’t enough previous research on the topic
• You want to report a wider range out of outcome when doing your research project
• You want to conduct a more open ended inquiries 

Perhaps the biggest drawback with research questions is that they tend to researchers in a position to “fish expectations” or excessively manipulate their findings.

Again, research questions sometimes tend to be less specific, and the reason is that there often no sufficient previous research on the questions.

What’s a Hypothesis? 

A hypothesis is a statement you can approve or disapprove. You develop a hypothesis from a research question by changing the question into a statement.

Primarily applied in deductive research, it involves the use of scientific, mathematical, and sociological findings to agree to or write off an assumption.

Researchers use the null approach for statements they can disapprove. They take a hypothesis and add a “not” to it to make it a working null hypothesis.

A null hypothesis is quite common in scientific methods. In this case, you have to formulate a hypothesis, and then conduct an investigation to disapprove the statement.

If you can disapprove the statement, you develop another hypothesis and then repeat the process until you can’t disapprove the statement.

In other words, if a hypothesis is true, then it must have been repeatedly tested and verified.

The consensus among researchers is that, like research questions, a hypothesis should not only be clear and easy to understand but also have a definite focus, answerable, and relevant to your field of study. 

When is a Hypothesis Useful?

A hypothesis may be useful when or if:

• There’s enough previous research on the topic
• You want to test a specific model or a particular theory
• You anticipate a likely outcome in advance 

The drawback to hypothesis as a scientific method is that it can hinder flexibility, or possibly blind a researcher not to see unanticipated results.

Research Question vs Hypothesis: Which One Should Come First 

Researchers use scientific methods to hone on different theories. So if the purpose of the research project were to analyze a concept, a scientific method would be necessary.

Such a case requires coming up with a research question first, followed by a scientific method.

Since a hypothesis is part of a research method, it will come after the research question.

Research Question vs Hypothesis: What’s the Difference? 

The following are the differences between a research question and a hypothesis.

We look at the differences in purpose and structure, writing, as well as conclusion. 

Research Questions vs Hypothesis: Some Useful Advice 

As much as there are differences between hypothesis and research questions, you have to state either one in the introduction and then repeat the same in the conclusion of your research paper.

Whichever element you opt to use, you should clearly demonstrate that you understand your topic, have achieved the goal of your research project, and not swayed a bit in your research process.

If it helps, start and conclude every chapter of your research project by providing additional information on how you’ve or will address the hypothesis or research question.

You should also include the aims and objectives of coming up with the research question or formulating the hypothesis. Doing so will go a long way to demonstrate that you have a strong focus on the research issue at hand.

Hypothesis vs. Research Question

What's the difference.

Hypothesis and research question are both essential components of the scientific research process, but they serve different purposes. A research question is a broad inquiry that aims to explore a specific topic or problem. It is often open-ended and seeks to gather information and generate knowledge. On the other hand, a hypothesis is a specific statement that predicts the relationship between variables or the outcome of a study. It is based on existing knowledge or theories and is testable through empirical research. While a research question guides the overall direction of a study, a hypothesis provides a more focused and specific prediction that can be tested and validated.

Further Detail

Introduction.

When conducting research, whether in the scientific or social sciences realm, it is essential to have a clear direction and purpose. Two key components that help guide the research process are the hypothesis and research question. While both serve as important tools in formulating and conducting research, they differ in their nature, purpose, and structure. In this article, we will explore the attributes of hypothesis and research question, highlighting their similarities and differences.

A hypothesis is a statement that proposes a relationship between variables or predicts an outcome based on existing knowledge or theories. It is an educated guess or assumption that guides the research process and helps researchers test their theories. Hypotheses are typically formulated in a declarative form, stating the expected relationship or outcome.

One of the key attributes of a hypothesis is that it is testable. This means that it can be empirically examined and either supported or rejected through data analysis. A hypothesis should be specific and precise, clearly defining the variables involved and the expected relationship between them. It should also be falsifiable, meaning that it can be proven wrong if the data does not support it.

Hypotheses are often used in quantitative research, where researchers aim to measure and analyze data to draw conclusions. They provide a framework for designing experiments or surveys and guide the collection and analysis of data. Hypotheses can be either directional, predicting the direction of the relationship between variables, or non-directional, suggesting that a relationship exists without specifying its direction.

For example, in a study examining the effects of exercise on mental health, a directional hypothesis could be: "Increased physical exercise will lead to a decrease in symptoms of anxiety." On the other hand, a non-directional hypothesis could be: "There is a relationship between physical exercise and symptoms of anxiety."

Research Question

A research question, on the other hand, is an inquiry that guides the research process and seeks to explore a specific topic or phenomenon. It is a broad, open-ended question that does not propose a specific relationship or outcome. Research questions are often used in qualitative research, where the focus is on understanding and interpreting social phenomena.

Unlike hypotheses, research questions do not require a definitive answer or prediction. Instead, they aim to explore and generate knowledge about a particular subject. Research questions are often formulated using words like "how," "what," "why," or "in what way," indicating the intention to investigate and understand a phenomenon.

Research questions are typically more flexible and adaptable than hypotheses. They allow researchers to explore multiple perspectives and gather rich, in-depth data. Research questions can evolve and change throughout the research process as new insights emerge. They provide a framework for qualitative data collection methods such as interviews, observations, or focus groups.

For example, in a study exploring the experiences of individuals living with chronic pain, a research question could be: "How do individuals with chronic pain cope with their condition on a daily basis?" This question allows for a comprehensive exploration of coping mechanisms, experiences, and challenges faced by individuals living with chronic pain.

Similarities and Differences

While hypotheses and research questions serve distinct purposes, they also share some similarities. Both hypotheses and research questions are essential components of the research process, providing a clear focus and direction. They both aim to guide the research and generate new knowledge. Additionally, both hypotheses and research questions should be grounded in existing literature and theories, ensuring that the research contributes to the existing body of knowledge.

However, the main difference between hypotheses and research questions lies in their structure and purpose. Hypotheses are more specific and focused, proposing a relationship or outcome that can be tested and analyzed quantitatively. They are often used in experimental or survey-based research designs. On the other hand, research questions are broader and open-ended, allowing for qualitative exploration and interpretation of social phenomena. They are commonly used in qualitative research designs.

Another difference is that hypotheses are often derived from research questions. Researchers start with a research question and then formulate a hypothesis based on existing knowledge and theories. The hypothesis provides a more specific and testable statement that can be examined through data analysis. In this way, hypotheses can be seen as a more refined version of research questions, focusing on a specific aspect of the research topic.

Furthermore, hypotheses are more commonly used in deductive research, where researchers start with a theory and test it through empirical evidence. Research questions, on the other hand, are often used in inductive research, where researchers gather data and generate theories or explanations based on the observed patterns or themes.

It is important to note that both hypotheses and research questions can coexist in a research study. In some cases, a study may have both a research question and a hypothesis. The research question provides a broader context and exploration of the topic, while the hypothesis allows for a more focused investigation of a specific relationship or outcome.

In conclusion, hypotheses and research questions are vital components of the research process, providing guidance and direction. While they share similarities in terms of their contribution to knowledge generation and grounding in existing literature, they differ in their structure, purpose, and application. Hypotheses are specific, testable statements that propose a relationship or outcome, often used in quantitative research. Research questions, on the other hand, are broad, open-ended inquiries that guide qualitative research and aim to explore and understand social phenomena. Both hypotheses and research questions play crucial roles in advancing research and expanding our understanding of the world.

Research Questions & Hypotheses

Generally, in quantitative studies, reviewers expect hypotheses rather than research questions. However, both research questions and hypotheses serve different purposes and can be beneficial when used together.

Research Questions

Clarify the research’s aim (farrugia et al., 2010).

• Research often begins with an interest in a topic, but a deep understanding of the subject is crucial to formulate an appropriate research question.
• Descriptive: “What factors most influence the academic achievement of senior high school students?”
• Comparative: “What is the performance difference between teaching methods A and B?”
• Relationship-based: “What is the relationship between self-efficacy and academic achievement?”
• Increasing knowledge about a subject can be achieved through systematic literature reviews, in-depth interviews with patients (and proxies), focus groups, and consultations with field experts.
• Some funding bodies, like the Canadian Institute for Health Research, recommend conducting a systematic review or a pilot study before seeking grants for full trials.
• The presence of multiple research questions in a study can complicate the design, statistical analysis, and feasibility.
• It’s advisable to focus on a single primary research question for the study.
• The primary question, clearly stated at the end of a grant proposal’s introduction, usually specifies the study population, intervention, and other relevant factors.
• The FINER criteria underscore aspects that can enhance the chances of a successful research project, including specifying the population of interest, aligning with scientific and public interest, clinical relevance, and contribution to the field, while complying with ethical and national research standards.
• The P ICOT approach is crucial in developing the study’s framework and protocol, influencing inclusion and exclusion criteria and identifying patient groups for inclusion.
• Defining the specific population, intervention, comparator, and outcome helps in selecting the right outcome measurement tool.
• The more precise the population definition and stricter the inclusion and exclusion criteria, the more significant the impact on the interpretation, applicability, and generalizability of the research findings.
• A restricted study population enhances internal validity but may limit the study’s external validity and generalizability to clinical practice.
• A broadly defined study population may better reflect clinical practice but could increase bias and reduce internal validity.
• An inadequately formulated research question can negatively impact study design, potentially leading to ineffective outcomes and affecting publication prospects.

Checklist: Good research questions for social science projects (Panke, 2018)

Research Hypotheses

Present the researcher’s predictions based on specific statements.

• These statements define the research problem or issue and indicate the direction of the researcher’s predictions.
• Formulating the research question and hypothesis from existing data (e.g., a database) can lead to multiple statistical comparisons and potentially spurious findings due to chance.
• The research or clinical hypothesis, derived from the research question, shapes the study’s key elements: sampling strategy, intervention, comparison, and outcome variables.
• Hypotheses can express a single outcome or multiple outcomes.
• After statistical testing, the null hypothesis is either rejected or not rejected based on whether the study’s findings are statistically significant.
• Hypothesis testing helps determine if observed findings are due to true differences and not chance.
• Hypotheses can be 1-sided (specific direction of difference) or 2-sided (presence of a difference without specifying direction).
• 2-sided hypotheses are generally preferred unless there’s a strong justification for a 1-sided hypothesis.
• A solid research hypothesis, informed by a good research question, influences the research design and paves the way for defining clear research objectives.

Types of Research Hypothesis

• In a Y-centered research design, the focus is on the dependent variable (DV) which is specified in the research question. Theories are then used to identify independent variables (IV) and explain their causal relationship with the DV.
• Example: “An increase in teacher-led instructional time (IV) is likely to improve student reading comprehension scores (DV), because extensive guided practice under expert supervision enhances learning retention and skill mastery.”
• Hypothesis Explanation: The dependent variable (student reading comprehension scores) is the focus, and the hypothesis explores how changes in the independent variable (teacher-led instructional time) affect it.
• In X-centered research designs, the independent variable is specified in the research question. Theories are used to determine potential dependent variables and the causal mechanisms at play.
• Example: “Implementing technology-based learning tools (IV) is likely to enhance student engagement in the classroom (DV), because interactive and multimedia content increases student interest and participation.”
• Hypothesis Explanation: The independent variable (technology-based learning tools) is the focus, with the hypothesis exploring its impact on a potential dependent variable (student engagement).
• Probabilistic hypotheses suggest that changes in the independent variable are likely to lead to changes in the dependent variable in a predictable manner, but not with absolute certainty.
• Example: “The more teachers engage in professional development programs (IV), the more their teaching effectiveness (DV) is likely to improve, because continuous training updates pedagogical skills and knowledge.”
• Hypothesis Explanation: This hypothesis implies a probable relationship between the extent of professional development (IV) and teaching effectiveness (DV).
• Deterministic hypotheses state that a specific change in the independent variable will lead to a specific change in the dependent variable, implying a more direct and certain relationship.
• Example: “If the school curriculum changes from traditional lecture-based methods to project-based learning (IV), then student collaboration skills (DV) are expected to improve because project-based learning inherently requires teamwork and peer interaction.”
• Hypothesis Explanation: This hypothesis presumes a direct and definite outcome (improvement in collaboration skills) resulting from a specific change in the teaching method.
• Example : “Students who identify as visual learners will score higher on tests that are presented in a visually rich format compared to tests presented in a text-only format.”
• Explanation : This hypothesis aims to describe the potential difference in test scores between visual learners taking visually rich tests and text-only tests, without implying a direct cause-and-effect relationship.
• Example : “Teaching method A will improve student performance more than method B.”
• Explanation : This hypothesis compares the effectiveness of two different teaching methods, suggesting that one will lead to better student performance than the other. It implies a direct comparison but does not necessarily establish a causal mechanism.
• Example : “Students with higher self-efficacy will show higher levels of academic achievement.”
• Explanation : This hypothesis predicts a relationship between the variable of self-efficacy and academic achievement. Unlike a causal hypothesis, it does not necessarily suggest that one variable causes changes in the other, but rather that they are related in some way.

Tips for developing research questions and hypotheses for research studies

• Perform a systematic literature review (if one has not been done) to increase knowledge and familiarity with the topic and to assist with research development.
• Learn about current trends and technological advances on the topic.
• Seek careful input from experts, mentors, colleagues, and collaborators to refine your research question as this will aid in developing the research question and guide the research study.
• Use the FINER criteria in the development of the research question.
• Ensure that the research question follows PICOT format.
• Develop a research hypothesis from the research question.
• Ensure that the research question and objectives are answerable, feasible, and clinically relevant.

If your research hypotheses are derived from your research questions, particularly when multiple hypotheses address a single question, it’s recommended to use both research questions and hypotheses. However, if this isn’t the case, using hypotheses over research questions is advised. It’s important to note these are general guidelines, not strict rules. If you opt not to use hypotheses, consult with your supervisor for the best approach.

Research Question vs Hypothesis: Understanding the Core Differences

Navigating the world of research can sometimes feel like trying to find your way through a labyrinth. Two terms that often trip up budding researchers are the research question and the hypothesis.

They may seem similar at first glance, but they serve distinct purposes in the research process.

Let's break down their differences and see how each plays a unique role in scientific inquiry.

What is a Research Question?

A research question is essentially the backbone of your study. It's what you're setting out to explore and understand. Think of it as the guiding star that keeps your research focused and on track. But what makes a good research question?

Characteristics of a Good Research Question

Original and Interesting: Your question should spark curiosity not just in you but also in the wider research community.

Clear and Focused: It needs to be specific enough to be comprehensible and narrow enough to be answerable. A question that's too broad can overwhelm you, while one that's too narrow might not provide enough material for comprehensive study.

Researchable: The question must be practical in terms of the time and resources you have at your disposal.

Analytical: It should allow you to delve into an analysis of a problem rather than just describe it. This means it can't be answered with a simple "yes" or "no."

For example, instead of asking, "How do social media platforms affect mental health?" which is too broad, you could ask, "What effect do Instagram filters have on the self-esteem of teenagers aged 13-18?"

What is a Hypothesis?

A hypothesis , on the other hand, is a tentative answer to your research question. It's a statement that you can test through experimentation or observation. Think of it as an educated guess based on existing knowledge and preliminary research.

Characteristics of a Good Hypothesis

Testable: You should be able to design an experiment or study to test whether your hypothesis is true or false.

Falsifiable: It must be possible to prove the hypothesis wrong. If a hypothesis can't be disproved, it's not scientifically useful.

Specific: Like a research question, a good hypothesis is clear and focused. It should define the variables and the expected relationship between them.

For instance, if your research question is about the effect of Instagram filters on teenagers' self-esteem, your hypothesis could be, "Teenagers who use Instagram filters will have lower self-esteem compared to those who do not."

Research Question vs Hypothesis: The Key Differences

Research Question: Guides your study and defines what you are trying to find out.

Hypothesis: Provides a tentative answer to your research question that you can test.

Formulation

Research Question: Usually formulated as a question that needs investigation.

Hypothesis: Formulated as a statement predicting the outcome of your research.

Research Question: Broader in scope; it sets the stage for the research.

Hypothesis: Narrower in scope; it focuses on specific variables and their relationships.

How They Work Together

The research question and hypothesis are not mutually exclusive; they complement each other. The research question sets the direction of your study, outlining what you aim to discover. The hypothesis then narrows this focus, providing a specific statement that you can test to answer your research question.

Let's bring this home with an example . Suppose you're interested in the impact of sleep on academic performance.

Research Question: How does the amount of sleep affect the academic performance of high school students?

Hypothesis: High school students who sleep for at least 8 hours a night will have higher academic performance compared to those who sleep less than 8 hours.

Q: Can I have a research question without a hypothesis? A: Yes, some qualitative studies may not require a hypothesis, but having one helps provide a clear focus for your research.

Q: Should my research question be broad or narrow? A: It should be narrow enough to be answerable but broad enough to allow for comprehensive investigation.

Q: Can a hypothesis be proven true? A: In science, a hypothesis is never proven true; it is either supported or not supported by the data.

Understanding the differences between a research question and a hypothesis is crucial for anyone venturing into the world of research. While the research question sets the stage for what you aim to explore, the hypothesis provides a specific, testable prediction. Together, they form the backbone of any rigorous scientific inquiry. So, the next time you embark on a research project, make sure you have both a clear research question and a well-defined hypothesis to guide you through your academic journey.

Research Aims, Objectives & Questions

By: David Phair (PhD) and Alexandra Shaeffer (PhD) | June 2022

T he research aims , objectives and research questions (collectively called the “golden thread”) are arguably the most important thing you need to get right when you’re crafting a research proposal , dissertation or thesis . We receive questions almost every day about this “holy trinity” of research and there’s certainly a lot of confusion out there, so we’ve crafted this post to help you navigate your way through the fog.

Overview: The Golden Thread

• What is the golden thread
• What are research aims ( examples )
• What are research objectives ( examples )
• What are research questions ( examples )
• The importance of alignment in the golden thread

What is the “golden thread”?

The golden thread simply refers to the collective research aims , research objectives , and research questions for any given project (i.e., a dissertation, thesis, or research paper ). These three elements are bundled together because it’s extremely important that they align with each other, and that the entire research project aligns with them.

Importantly, the golden thread needs to weave its way through the entirety of any research project , from start to end. In other words, it needs to be very clearly defined right at the beginning of the project (the topic ideation and proposal stage) and it needs to inform almost every decision throughout the rest of the project. For example, your research design and methodology will be heavily influenced by the golden thread (we’ll explain this in more detail later), as well as your literature review.

The research aims, objectives and research questions (the golden thread) define the focus and scope ( the delimitations ) of your research project. In other words, they help ringfence your dissertation or thesis to a relatively narrow domain, so that you can “go deep” and really dig into a specific problem or opportunity. They also help keep you on track , as they act as a litmus test for relevance. In other words, if you’re ever unsure whether to include something in your document, simply ask yourself the question, “does this contribute toward my research aims, objectives or questions?”. If it doesn’t, chances are you can drop it.

Alright, enough of the fluffy, conceptual stuff. Let’s get down to business and look at what exactly the research aims, objectives and questions are and outline a few examples to bring these concepts to life.

Research Aims: What are they?

Simply put, the research aim(s) is a statement that reflects the broad overarching goal (s) of the research project. Research aims are fairly high-level (low resolution) as they outline the general direction of the research and what it’s trying to achieve .

Research Aims: Examples

True to the name, research aims usually start with the wording “this research aims to…”, “this research seeks to…”, and so on. For example:

“This research aims to explore employee experiences of digital transformation in retail HR.”   “This study sets out to assess the interaction between student support and self-care on well-being in engineering graduate students”  

As you can see, these research aims provide a high-level description of what the study is about and what it seeks to achieve. They’re not hyper-specific or action-oriented, but they’re clear about what the study’s focus is and what is being investigated.

Need a helping hand?

Research Objectives: What are they?

The research objectives take the research aims and make them more practical and actionable . In other words, the research objectives showcase the steps that the researcher will take to achieve the research aims.

The research objectives need to be far more specific (higher resolution) and actionable than the research aims. In fact, it’s always a good idea to craft your research objectives using the “SMART” criteria. In other words, they should be specific, measurable, achievable, relevant and time-bound”.

Research Objectives: Examples

Let’s look at two examples of research objectives. We’ll stick with the topic and research aims we mentioned previously.  

For the digital transformation topic:

To observe the retail HR employees throughout the digital transformation. To assess employee perceptions of digital transformation in retail HR. To identify the barriers and facilitators of digital transformation in retail HR.

And for the student wellness topic:

To determine whether student self-care predicts the well-being score of engineering graduate students. To determine whether student support predicts the well-being score of engineering students. To assess the interaction between student self-care and student support when predicting well-being in engineering graduate students.

  As you can see, these research objectives clearly align with the previously mentioned research aims and effectively translate the low-resolution aims into (comparatively) higher-resolution objectives and action points . They give the research project a clear focus and present something that resembles a research-based “to-do” list.

Research Questions: What are they?

Finally, we arrive at the all-important research questions. The research questions are, as the name suggests, the key questions that your study will seek to answer . Simply put, they are the core purpose of your dissertation, thesis, or research project. You’ll present them at the beginning of your document (either in the introduction chapter or literature review chapter) and you’ll answer them at the end of your document (typically in the discussion and conclusion chapters).

The research questions will be the driving force throughout the research process. For example, in the literature review chapter, you’ll assess the relevance of any given resource based on whether it helps you move towards answering your research questions. Similarly, your methodology and research design will be heavily influenced by the nature of your research questions. For instance, research questions that are exploratory in nature will usually make use of a qualitative approach, whereas questions that relate to measurement or relationship testing will make use of a quantitative approach.  

Let’s look at some examples of research questions to make this more tangible.

Research Questions: Examples

Again, we’ll stick with the research aims and research objectives we mentioned previously.  

For the digital transformation topic (which would be qualitative in nature):

How do employees perceive digital transformation in retail HR? What are the barriers and facilitators of digital transformation in retail HR?  

And for the student wellness topic (which would be quantitative in nature):

Does student self-care predict the well-being scores of engineering graduate students? Does student support predict the well-being scores of engineering students? Do student self-care and student support interact when predicting well-being in engineering graduate students?  

You’ll probably notice that there’s quite a formulaic approach to this. In other words, the research questions are basically the research objectives “converted” into question format. While that is true most of the time, it’s not always the case. For example, the first research objective for the digital transformation topic was more or less a step on the path toward the other objectives, and as such, it didn’t warrant its own research question.

So, don’t rush your research questions and sloppily reword your objectives as questions. Carefully think about what exactly you’re trying to achieve (i.e. your research aim) and the objectives you’ve set out, then craft a set of well-aligned research questions . Also, keep in mind that this can be a somewhat iterative process , where you go back and tweak research objectives and aims to ensure tight alignment throughout the golden thread.

The importance of strong alignment

Alignment is the keyword here and we have to stress its importance . Simply put, you need to make sure that there is a very tight alignment between all three pieces of the golden thread. If your research aims and research questions don’t align, for example, your project will be pulling in different directions and will lack focus . This is a common problem students face and can cause many headaches (and tears), so be warned.

Take the time to carefully craft your research aims, objectives and research questions before you run off down the research path. Ideally, get your research supervisor/advisor to review and comment on your golden thread before you invest significant time into your project, and certainly before you start collecting data .  

Recap: The golden thread

Thank you very much for your great effort put. As an Undergraduate taking Demographic Research & Methodology, I’ve been trying so hard to understand clearly what is a Research Question, Research Aim and the Objectives in a research and the relationship between them etc. But as for now I’m thankful that you’ve solved my problem.

Well appreciated. This has helped me greatly in doing my dissertation.

An so delighted with this wonderful information thank you a lot.

so impressive i have benefited a lot looking forward to learn more on research.

I am very happy to have carefully gone through this well researched article.

Infact,I used to be phobia about anything research, because of my poor understanding of the concepts.

Now,I get to know that my research question is the same as my research objective(s) rephrased in question format.

I please I would need a follow up on the subject,as I intends to join the team of researchers. Thanks once again.

Thanks so much. This was really helpful.

I know you pepole have tried to break things into more understandable and easy format. And God bless you. Keep it up

i found this document so useful towards my study in research methods. thanks so much.

This is my 2nd read topic in your course and I should commend the simplified explanations of each part. I’m beginning to understand and absorb the use of each part of a dissertation/thesis. I’ll keep on reading your free course and might be able to avail the training course! Kudos!

Thank you! Better put that my lecture and helped to easily understand the basics which I feel often get brushed over when beginning dissertation work.

This is quite helpful. I like how the Golden thread has been explained and the needed alignment.

This is quite helpful. I really appreciate!

The article made it simple for researcher students to differentiate between three concepts.

Very innovative and educational in approach to conducting research.

I am very impressed with all these terminology, as I am a fresh student for post graduate, I am highly guided and I promised to continue making consultation when the need arise. Thanks a lot.

A very helpful piece. thanks, I really appreciate it .

Very well explained, and it might be helpful to many people like me.

Wish i had found this (and other) resource(s) at the beginning of my PhD journey… not in my writing up year… 😩 Anyways… just a quick question as i’m having some issues ordering my “golden thread”…. does it matter in what order you mention them? i.e., is it always first aims, then objectives, and finally the questions? or can you first mention the research questions and then the aims and objectives?

Thank you for a very simple explanation that builds upon the concepts in a very logical manner. Just prior to this, I read the research hypothesis article, which was equally very good. This met my primary objective.

My secondary objective was to understand the difference between research questions and research hypothesis, and in which context to use which one. However, I am still not clear on this. Can you kindly please guide?

In research, a research question is a clear and specific inquiry that the researcher wants to answer, while a research hypothesis is a tentative statement or prediction about the relationship between variables or the expected outcome of the study. Research questions are broader and guide the overall study, while hypotheses are specific and testable statements used in quantitative research. Research questions identify the problem, while hypotheses provide a focus for testing in the study.

Exactly what I need in this research journey, I look forward to more of your coaching videos.

This helped a lot. Thanks so much for the effort put into explaining it.

What data source in writing dissertation/Thesis requires?

What is data source covers when writing dessertation/thesis

This is quite useful thanks

I’m excited and thankful. I got so much value which will help me progress in my thesis.

where are the locations of the reserch statement, research objective and research question in a reserach paper? Can you write an ouline that defines their places in the researh paper?

Very helpful and important tips on Aims, Objectives and Questions.

Thank you so much for making research aim, research objectives and research question so clear. This will be helpful to me as i continue with my thesis.

Thanks much for this content. I learned a lot. And I am inspired to learn more. I am still struggling with my preparation for dissertation outline/proposal. But I consistently follow contents and tutorials and the new FB of GRAD Coach. Hope to really become confident in writing my dissertation and successfully defend it.

As a researcher and lecturer, I find splitting research goals into research aims, objectives, and questions is unnecessarily bureaucratic and confusing for students. For most biomedical research projects, including ‘real research’, 1-3 research questions will suffice (numbers may differ by discipline).

Awesome! Very important resources and presented in an informative way to easily understand the golden thread. Indeed, thank you so much.

Well explained

The blog article on research aims, objectives, and questions by Grad Coach is a clear and insightful guide that aligns with my experiences in academic research. The article effectively breaks down the often complex concepts of research aims and objectives, providing a straightforward and accessible explanation. Drawing from my own research endeavors, I appreciate the practical tips offered, such as the need for specificity and clarity when formulating research questions. The article serves as a valuable resource for students and researchers, offering a concise roadmap for crafting well-defined research goals and objectives. Whether you’re a novice or an experienced researcher, this article provides practical insights that contribute to the foundational aspects of a successful research endeavor.

A great thanks for you. it is really amazing explanation. I grasp a lot and one step up to research knowledge.

I really found these tips helpful. Thank you very much Grad Coach.

I found this article helpful. Thanks for sharing this.

thank you so much, the explanation and examples are really helpful

This is a well researched and superbly written article for learners of research methods at all levels in the research topic from conceptualization to research findings and conclusions. I highly recommend this material to university graduate students. As an instructor of advanced research methods for PhD students, I have confirmed that I was giving the right guidelines for the degree they are undertaking.

This chapter deals with the important, but often neglected, issue of establishing research questions or hypotheses, whether this is done before or (in the “real world”) often after the study has been conducted. The point is made that, in fact, research questions tend to be more common than hypotheses in action research, and guidelines are suggested for delineating such questions and deciding on appropriate question types according to the research purpose. Some example questions are provided to stimulate ideas, and an example action research study which will proceed in stages throughout the book is begun here.

How To Write Clear Research Questions And Hypotheses

Quick Takeaways:

• et al.' means 'and others'.
• Use 'et al.' to cite works with three or more authors.
• The presentation (et al., et al., or rarely et al) depends on the style guide or journal guidelines

The English language has a rich history of borrowing words from other languages, especially from Latin. Latin abbreviations such as ‘a.m.’, ‘p.m.’ and ‘CV’ have become part of our everyday vocabulary. Such abbreviations are also frequently used in academic writing, from the ‘Ph.D.’ in the affiliation section to the ‘i.e.’, ‘e.g.’, ‘et al.’, and ‘QED’ in the rest of the paper.

This guide explains when and how to correctly use ‘et al.’ in a research paper.

In this guide:

• 1) Meaning of ‘et al.’
• a) Table: Correct use of ‘et al.’ by style guide
• b) Unusual scenarios

In  previous blogs  we have already covered how to write an introduction and literature review, and how to define the purpose and rationale for your study.

Depending on your field, you may need to write your research question and/or hypothesis before moving on to write the main body of your study. You don’t usually need to include both research question and hypothesis, unless you have several hypotheses that arise from the research question.

Important!  We are not suggesting that you come up with your research question or hypotheses at this stage: Your research question or hypotheses should actually have been developed before you conducted or even designed your study.

Here, we’re discussing how you can clearly state the research question or hypotheses.

What is a Research Question?

Your research question, or questions, should specifically state the purpose of your study in terms of the question you aim to answer. Its purpose is to guide and center your research study.

For example: If the purpose of your study is to evaluate the efficacy of a newly-developed intervention for treating anxiety, your research question might be something like:

“Is intervention A effective for treating people with anxiety?”

The research question above needs to be turned into a testable hypothesis. A hypothesis is a statement rather than a question, and it should make a  prediction  about what you expect to happen. This is referred to as a  directional  or  alternative hypothesis , and is often abbreviated as H 1 .

Continuing with the research question example above, the hypothesis might be written as:

“Participants who receive intervention A will show a significant reduction in scores on the Anxiety Scale from baseline to 6-week follow up.”

If your study uses a control group, the hypothesis can be modified to:

“Participants who receive intervention A will score significantly lower on the Anxiety Scale than participants in the wait-list control group.”

Bear in mind that  your hypothesis needs to be specific .

Continuing with the earlier example, if your hypothesis only states  “Participants who receive the intervention will be less anxious” , it is not specific enough because it does not state how you will know whether anxiety has been reduced or what “less” is in relation to.

Filling a Gap is Not a Rationale in itself

When you test a hypothesis, you actually  test the null hypothesis , which predicts no difference in the variables you are testing.

Some journals prefer you to state the null hypothesis, often abbreviated as H 0 , or both the null and alternative.

The corresponding null forms of our example hypotheses are:

“Participants who receive intervention A will show no difference in anxiety scores from baseline to 6-week follow-up.”

“Participants who receive intervention A will show no difference in anxiety scores from participants in the wait-list control group.”

More examples of Research Questions and Hypotheses

Your research questions and hypotheses are likely to be quite different from our examples depending on the type of your study. We present some examples below for your reference.

Case 1:  Experimental study examining the effect of one (or more) independent variable(s) on a dependent variable Research Question:   “Does substance A affect the appetite of rats?” Directional or Alternative Hypothesis:   “Rats that receive an injection of substance A will consume significantly more food than rats that do not receive the injection.” Null Hypothesis:   “Rats that receive an injection of substance A will show no difference in food consumption from those that do not receive the injection.”

Case 2:  Correlational study examining the relationships among variables Research Question:   “Does spending time outdoors influence how satisfied people feel with their lives?” Directional or Alternative Hypothesis:   “There is a significant positive relationship between the weekly amount of time spent outdoors and self-reported levels of satisfaction with life.” Null Hypothesis:   “There is no relationship between the weekly amount of time spent outdoors and self-reported levels of satisfaction with life.”

Tips when you are writing several hypotheses, or stating both the null and alternative in your paper

I.  It is clearer to the reader if you make the wording for your hypotheses as similar as possible to each other. So, use the same key phrases and terms: rather than making the writing more interesting, varying the use of key terms always causes confusion.

II.  Try to position the variables so that the independent variable appears first in the sentence, then the dependent variable. This word order reflects the hypothesised direction of the effect and is therefore clearer than the reverse order.

• “Significantly more food will be consumed by rats that receive an injection of substance A than by rats that do not receive the injection.”
• “Rats that receive an injection of substance A will consume significantly more food than rats that do not receive the injection.”

QUICK ASIDE

Wondering why some abbreviations such as ‘et al.’ and ‘e.g.’ use periods, whereas others such as CV and AD don’t? Periods are typically used if the abbreviations include lowercase or mixed-case letters. They’re usually not used with abbreviations containing only uppercase letters.

Unusual Scenarios

Our latest online workshop built on the success of face-to-face workshops we developed specifically for local universities. Over 30 faculty members joined the session, presented by our Chief Operating Officer, Mr Nick Case, to learn from our case studies on editing research proposals.

The response to our workshop, which included a constructive and insightful Q&A session, was very positive.Drawing on our extensive experience working with hundreds of Hong Kong researchers targeting the GRF and ECS every year, we used examples of poor and subsequently improved proposals to show the attendees how they can make their applications stand out.

Research Questions, Hypotheses and Objectives

Research questions.

A research question naturally emerges from a research problem that needs to be resolved. Developing a good research question not only rests on the study of some uncertain phenomenon, but also on the rational need for investigating it. It is therefore essential that a systematic review of extant literature on the research topic be conducted, prior to formulating a research question. Awareness of current trends and latest development in the field of study will certainly assist in formulating a relevant question. There may be several research questions, whether primary or secondary, but they should all be developed during the planning stage of a study. Furthermore, it must be ensured that secondary questions do not compromise the primary research question, which forms the basis of research objectives and hypotheses. Lastly, bear in mind that the number of research questions will inevitably make the research design and data analysis more complex.

Hulley et al . (2001) suggested the use of the FINER criteria in developing a good research question:

• F - Feasible : adequate number of subjects and technical expertise, affordability in terms of time and money, manageability in scope
• I - Interesting : getting an answer that intrigues the researcher, the peers and the community
• N - Novel : confirms, refutes or extends previous findings
• E - Ethical : a study that will be approved by an institutional review board
• R - Relevant : to scientific knowledge and future research

A poorly formulated research question may thus affect the choice of study design and hamper the chance of obtaining any significant finding, besides compromising the quality of the study.

Research Hypotheses

First of all, it is essential to understand that it is a hypothesis, not the data, that drives a primary research question . Otherwise, given any dataset, it would be too simple to perform several tests and apply statistical techniques to establish significant associations and/or relationships among variables and/or constructs. In such cases, it would be working backward by using the data to develop the research question, and that would defeat the entire purpose of conducting the study. To make matters worse, spuriously positive findings may result.

Hypothesis testing aims at making inferences about the targeted population on the basis of a random sample taken from that population. A hypothesis must be formulated as a null hypothesis, generally meaning that a prevailing situation has not changed (in the case of finding differences) or that there are no significant relationships among variables and/or constructs. This is the reason why each null hypoythesis must be paired with an alternative hypothesis, should the outcome be significant. The two hypotheses must be mutually exclusive and comprehensively exhaustive, i.e., the acceptance of one would automatically imply the rejection of the other. For a better understanding of the concept of hypothesis testing, you might need to consult our statistician.

At this stage, all you need to know is that the development of a research hypothesis should be supported by a good research question, as it will influence your research design. Once appropriate hypotheses have been developed, you can safely proceed to the formulation of your research objectives.

Research Objectives

You must first learn to distinguish between a research aim and a research objective . While an aim is written in broad terms and explains what is to be achieved at the end of the study, an objective is an active statement that is defined in measurable outcomes via a strong positive statement. The primary objective of a study is paired with the hypothesis of the study, and should be clearly stated in the introduction of the research protocol. Objectives usually state exactly the outcome measures that are going to be used within their statements. Strong verbs like determine , measure , assess , evaluate , identify , examine , investigate , etc., are used in the formulation of objectives.

The importance of objectives is that they guide the development of the protocol and design of study, and play a determining role in sample size calculations. Objectives should be focused on outcomes that are important and relevant to the study.

Research aim To investigate the issue of student indiscipline and its impact on student attainment in Mauritian Secondary Schools Research question What are the various types of student indiscipline currently experienced in secondary schools of Mauritius? Research (null) hypothesis School management style does not impact on student attainment Research objective To identify the most common forms of indiscipline and their level of seriousness
