Module 5: Paired Sample Ttest

Module Introduction

This week turn our attention to a paired sample t-test. This test is usually the most widely known (or at least most students understand the concept) because it applies to situations where we have a pre/post test data. To be sure, there are other ways we can use this type of test, but most are familiar with the pre/post test design. Keep in mind, since this is a ttest, we are again looking for differences in means!
