Tests for paired or multiple measurements of the same variable

These techniques are used when you have collected the same variable on the same people at different time points. Example: Test the difference in cholesterol after a trial of a specific margarine by measuring cholesterol before and after the trial on each participant. Note:If the assumptions for the t-test or repeated measures ANOVA have not been met, use the equivalent non-parametric test.
