what does the alternative hypothesis mean

What is an alternative hypothesis? The alternative hypothesis (H a) is the other answer to your research question. It claims that there’s an effect in the population. Often, your alternative hypothesis is the same as your research hypothesis. In other words, it’s the claim that you expect or hope will be true. The alternative hypothesis is ...

Alternative hypothesis (HA): The sample data suggests that the assumption made in the null hypothesis is not true. In other words, there is some non-random cause influencing the data. There are two types of alternative hypotheses: A one-tailed hypothesis involves making a “greater than” or “less than ” statement.

In statistics, alternative hypothesis is often denoted as Ha or H1. Hypotheses are formulated to compare in a statistical hypothesis test. In the domain of inferential statistics, two rival hypotheses can be compared by explanatory power and predictive power.

H a —, the alternative hypothesis: a claim about the population that is contradictory to H 0 and what we conclude when we reject H 0. Since the null and alternative hypotheses are contradictory, you must examine evidence to decide if you have enough evidence to reject the null hypothesis or not.

Alternate hypothesis: President re-elected with 1-2 percent majority. Although the outcome hasn’t changed (the President is still re-elected), the majority percentage has changed—which may be important to an electoral campaign. The alternate hypothesis is usually what you will be testing in hypothesis testing.

a statement about the value of a population parameter, in case of two hypotheses, the statement assumed to be true is called the null hypothesis (notation \(H_{0}\)) and the contradictory statement is called the alternative hypothesis (notation \(H_{a}\)).

In a statistical test, observed data is used to decide whether or not to reject a restriction on the data-generating probability distribution. The assumption that the restriction is true is called null hypothesis, while the statement that the restriction is not true is called alternative hypothesis.

H a: The alternative hypothesis: It is a claim about the population that is contradictory to H 0 and what we conclude when we reject H 0. Since the null and alternative hypotheses are contradictory, you must examine evidence to decide if you have enough evidence to reject the null hypothesis or not.

The alternative hypothesis is simply the reverse of the null hypothesis, and there are three options, depending on where we expect the difference to lie. Thus, our alternative hypothesis is the mathematical way of stating our research question.

The alternative hypothesis is one of two mutually exclusive hypotheses in a hypothesis test. The alternative hypothesis states that a population parameter does not equal a specified value. Typically, this value is the null hypothesis value associated with no effect, such as zero.
