Paired t-test

Introduction

Paired t-tests are used to test for a difference between paired population means. The data from these studys are often collected on the same sampling units (individuals or objects) at different times, for example, heart rate measurements taken before and after a stress test. These measurements performed on the same sampling units are correlated, so they are handled differently than independent measurements taken from two sampling units.
