Explain how hypothesis tests differ across experiments and correlational studies.
What will be an ideal response?
Hypothesis tests differ for experiments and correlational studies in the way hypotheses are made and the inferential statistics that are calculated. In correlational studies, we make hypotheses about relationships and whether they are positive or negative instead of about mean differences. We then test the null hypothesis using tests designed to tell us about the strength and direction of the relationship that exists between two measured variables, such as a Pearson r test.
