In a study, should a researcher formulate many different questions/subquestions which require different data analyses? For my proposal, I have thought out a repeated measures, pre/post-test design using t-tests. I wanted to use t-tests to test for significance between the pre/post-tests after the intervention, and I was planning on reporting the test statistic, degrees of freedom, p value, and effect size. It wouldn't make sense to also test for multiple regression controlling for covariates, would it? If so, then I would add an additional RQ to go with that data analyses, correct
