Quizplus · Accepted Answer

The degrees of freedom for the interaction of factors A and B in a two-factor between-subjects ANOVA are calculated using the formula (a-1)(b-1), where a is the number of levels of factor A and b is the number of levels of factor B. This formula takes into account the number of independent groups within each level of both factors. Therefore, the correct answer is (a-1)(b-1).
