- The three assumptions for ANOVA are: (1) homogeneity of variance; (2) normally distributed scores; (3) independence of observations.
- H0 for ANOVA implies that the means of the different scores are equal.
To test this hypothesis, you use the F-test in which the F statistic is calculated by MStreatment / MSerror. The associated p-value can be found in appendix F with the corresponding degrees of freedom.
- The degrees of freedom in ANOVA are: k - 1 and k*(n-1) with n the number of participants per group.
