[10h] Name this statistical condition where the variances of the differences between all combinations of related groups are equal. Mauchly's W is a statistical test to validate this condition.

ANSWER: sphericity [prompt on epsilon-hat; reject “epsilon”]

[10m] Sphericity, normality, and randomness are the three univariate assumptions of the repeated-measures type of this test. The ratio of between-group and within-group variability equals the F-statistic in this statistical test.

ANSWER: ANOVA [or analysis of variance; accept repeated-measures ANOVA or rANOVA]
