Quizplus · Accepted Answer

Two-way ANOVAs can answer questions about the effects of two factors on a dependent variable and whether there is an interaction between the factors. However, they do not specifically address whether one level of a factor affects the dependent variable significantly more than others, which would require post-hoc tests or planned contrasts.
