Determining Cutoffs for an F Distribution We determine the critical values for an F distribution for a two-way between-groups ANOVA just as we did for a one-way between-groups ANOVA, except that we calculate three cutoffs, one for each main effect and one for the interaction. In this case, the between-groups degrees of freedom are the same for all three, so the cutoffs are the same.
