Null and alternative hypotheses are similar in some ways: 1. They’re both answers to the research question. 2. They both make claims about the population. 3. They’re both evaluated by statistical tests. However, there are important differences between the two types of hypotheses, summarized in the following table. See more The null and alternative hypotheses offer competing answers to your research question. When the research question asks “Does the independent variable affect the dependent variable?”: 1. The null hypothesis (H0) … See more The null hypothesis is the claim that there’s no effect in the population. If the sample provides enough evidence against the claim that there’s no effect in the population (p ≤ α), then we can reject the null hypothesis. … See more The alternative hypothesis (Ha) is the other answer to your research question. It claims that there’s an effect in the population. Often, … See more To help you write your hypotheses, you can use the template sentences below. If you know which statistical test you’re going to use, you can use the test-specific template sentences. … See more WebNull and alternative hypotheses are used in statistical hypothesis testing. The null hypothesis of a test always predicts no effect or no relationship between variables, while …
