Quizplus · Accepted Answer

The interaction degrees of freedom for a two-way ANOVA can be calculated using the formula (a-1) x (b-1), where a is the number of levels of Factor A and b is the number of levels of Factor B. Therefore, the interaction degrees of freedom in this case would be (5-1) x (7-1) = 24. Therefore, the correct choice is C.
