To calculate the F for the interaction in an ANOVA, we need to divide the mean square for the interaction by the mean square for the error term. This gives us the ratio of the variability due to the interaction effect to the residual variability. Therefore, A is the correct choice as it divides MS _interaction by MS _error.
