May I please get a simple explanation of these questions, if possible ? Thank you!
1) What are the pros and cons of the independent and dependent samples t-tests?
2) Be able to describe the assumptions of the two-samples t-tests.
3) When should you calculate and use a "weighted average" for pooled variance in an inferential t-test?
4) All things being equal, is it more likely to reject the null in a z-test of a t-test?
