Research Hypothesis In Psychology: Types, & Examples
Learn what a research hypothesis is, how to write one, and the types of hypotheses used in psychology. The alternative hypothesis predicts a relationship between two variables, while the null hypothesis predicts no relationship.
Null & Alternative Hypotheses
Learn how to write null and alternative hypotheses for different statistical tests and research questions. The null hypothesis claims no effect in the population, while the alternative hypothesis claims an effect.
7.4: The Alternative Hypothesis
Thus, our alternative hypothesis is the mathematical way of stating our research question. If we expect our obtained sample mean to be above or below the null hypothesis value, which we call a directional hypothesis, then our alternative hypothesis takes the form: HA: μ> 7.47 or HA: μ <7.47 H A: μ> 7.47 or H A: μ <7.47.

Null and Alternative Hypotheses
Learn how to write null and alternative hypotheses for different statistical tests in psychology and other fields. The null hypothesis claims there's no effect in the population, while the alternative hypothesis claims there is an effect.
Alternative hypothesis
The alternative hypothesis and null hypothesis are types of conjectures used in statistical tests, which are formal methods of reaching conclusions or making judgments on the basis of data. In statistical hypothesis testing, the null hypothesis and alternative hypothesis are two mutually exclusive statements. "The statement being tested in a test of statistical significance is called the null ...

Alternative hypothesis: If the null hypothesis is rejected, then we will need some other explanation, which we call the alternative hypothesis, H A or H 1. The alternative hypothesis is simply the reverse of the null hypothesis. ... and in their introductory psychology textbook, Gerrig & Zimbardo (2002) referred to NHST as the "backbone of ...

Generally, it is a scientific prediction of significant results in hypothesis testing; that is, an alternative hypothesis posits meaningful differences or relationships between the variables under investigation.
Chapter 9.4 Alternative & the Null Hypothesis
The null hypothesis states that there is no change or difference as a result of the independent variable. In other words, work experience does not result in a difference in grades among college students. The alternative hypothesis states that there is a change or difference. When we perform statistics, we are always testing for the null and ...

8.1: The null and alternative hypotheses
Alternative hypothesis. Alternative hypothesis \(\left(H_{A}\right)\): If we conclude that the null hypothesis is false, or rather and more precisely, we find that we provisionally fail to reject the null hypothesis, then we provisionally accept the alternative hypothesis.The view then is that something other than random chance has influenced the sample observations.
Why we habitually engage in null-hypothesis significance testing: A
This idea is referred to as the alternative hypothesis (H1). Its complement, the null hypothesis (H0), typically assumes no association or effect (although it is possible to test other effect sizes than no effect with the null hypothesis). ... In 2015, the editors of the journal 'Basic and Applied Social Psychology' (BASP) prohibited the ...

Introduction to Hypothesis Testing (Psychology)
The null hypothesis is the statement or claim being made (which we are trying to disprove) and the alternative hypothesis is the hypothesis that we are trying to prove and which is accepted if we have sufficient evidence to reject the null hypothesis.

Alternative Hypothesis (H1): This is what you want to test. It suggests there is a change or effect. Example: Suppose a company says their new batteries last an average of 500 hours. To check this: Null Hypothesis (H0): The average battery life is 500 hours. Alternative Hypothesis (H1): The average battery life is not 500 hours. 2. Choose the Test
Understanding Null Hypothesis Testing
Therefore, they rejected the null hypothesis in favor of the alternative hypothesis—concluding that there is a positive correlation between these variables in the population. A crucial step in null hypothesis testing is finding the probability of the sample result or a more extreme result if the null hypothesis were true (Lakens, 2017). [1]
13.1 Understanding Null Hypothesis Testing
A crucial step in null hypothesis testing is finding the likelihood of the sample result if the null hypothesis were true. This probability is called the p value. A low p value means that the sample result would be unlikely if the null hypothesis were true and leads to the rejection of the null hypothesis. A high p value means that the sample ...
