I introduce the basics of setting up a significance test, such as defining a null and alternative hypothesis, checking conditions, etc. I finish by working through an example of a matched pairs t-test. EXAMPLE AT 19:00 Please note these changes in wording of my example: Normality: With difference being fairly symmetric & unimodal, the CLT will ensure the sampling distribution of sample means will be approximately Normal. Definition of Mu should be Mean of difference in Post Test and PreTest.
