In a concise analytical response, outline the three sequential steps a researcher follows in the structured logic of null hypothesis testing, starting from the baseline assumption.
Question: In a concise analytical response, outline the three sequential steps a researcher follows in the structured logic of null hypothesis testing, starting from the baseline assumption.
Sample answer: The structured logic of null hypothesis testing consists of three steps. First, the researcher assumes that the null hypothesis is true. Second, they calculate how likely or probable their sample results would be under this assumption. Third, based on this calculated probability, they decide to either reject or retain the null hypothesis.
Key points:
- Assume the null hypothesis is true.
- Calculate how likely the sample results would be if the null hypothesis were true.
- Decide to reject or retain the null hypothesis based on the calculated probability.
Rubric: Full credit requires the student to correctly identify and sequence the three main logical steps: assuming the null hypothesis is true, calculating the likelihood of the sample results under this assumption, and making a decision to reject or retain the null hypothesis.
