Overview

The repeated measures design is also known as a within-subject design. In this ANOVA design, participants present scores for each of the conditions in the study. These repeated conditions may include the same measure repeated over time, or across conditions for each participant, or it may involve the measure and comparison of several related factors for each participant.

Assumptions

• Sphericity: Instead of the homogeneity of variance assumption (which is part of one-way (between-subjects) and factorial ANOVA designs, repeated-measures designs have the assumption of sphericity, tested by Mauchly's test.
