The paired t-test (also called the correlated t-test and the t-test for dependent means) is used to ascertain how likely the difference between two means that contain the same (or matched) observations is to occur by chance alone. These means may represent pretest–posttest differences involving the same group of subjects, posttest differences when subjects are randomly assigned to two groups in pairs based upon a pre-existing variable (or a pretest), or differences between two scores available on the same group of subjects in non-experimental research.
