SPHERICITY IN REPEATED MEASURES ANALYSIS OF …

When you conduct an analysis of variance with a repeated measures factor (within-subjects independent variable), you need to examine the concept of sphericity. This is an assumption of a repeated measures ANOVA (RM ANOVA) – and violations of this assumption can affect the conclusions drawn from your analysis. What is Sphericity?
