Repeated Measures ANOVA & Sphericity – Practice Quiz

Understand the covariance reasoning behind repeated-measures ANOVA. Prerequisites: paired contrasts, variance-covariance calculations and factorial ANOVA. Distinguish compound symmetry from sphericity, interpret Mauchly diagnostics and apply Greenhouse-Geisser or Huynh-Feldt reference corrections. Worked examples and counterexamples address difference variances, epsilon, order effects, missing visits and covariance-aware alternatives.
