This is for means: p value for homogeneity of variance tests (you want p to be larger than . 05 because the variances will not be different between the groups) this is for variance. Means you can explain any variance because you accounted for it in the model!: because there is no variance among groups and between different people, effect size: how much one variable affects another. Someone collects data during a study (or experiment) and infers information from their sample using descriptive statistics (the mean and variance). If you have 2 groups (exercise and diet) you would get 3 f values (1 for exercise, 1 for diet, 1 for the interaction effect)
