Analysis of variance with repeated measurement tests whether there are statistically significant differences in three or more dependent samples. The one-factor analysis of variance with repeated measures is the extension of the t-test for dependent samples for more than two groups.

In the t-test for dependent samples, we examined whether there is a difference between two dependent groups. If we want to test whether there is a difference between more than two dependent groups, we use the analysis of variance with repeated measures.
