WebTesting sphericity The sphericity assumption is essentially the repeated measures ANOVA equivalent of homogeneity of variances. Sphericity means there is equality of variances of the differences between treatment levels. WebAug 24, 2024 · Mauchly’s test of sphericity is used to test whether or not the assumption of sphericity is met in a repeated measures ANOVA. Sphericity refers to the condition where the variances of the differences between all combinations of related groups are equal. If this assumption is violated, then the F-ratio becomes inflated and the results of the ...
