### Repeated Measures ANOVA

Therefore, we could report the main finding as: → Mauchly's test indicated that the assumption of sphericity had been violated, χ 2 (5) = 11.41, p < .05, therefore degrees of freedom were corrected using Greenhouse-**Geisser** estimates of sphericity (ε = .53).

### Repeated Measures 1

Several corrections have been proposed, most notably the Greenhouse-**Geisser** and Huynh-Feldt epsilon corrections. These do not affect the computed F -statistic, but instead raise the critical F value needed to reject the null hypothesis.
