Quizplus · Accepted Answer

In a 2 × 3 analysis of variance, there are three main effects: two for the first factor (with two levels) and one for the second factor (with three levels). Additionally, there are three possible interactions: between the first factor and the second factor, within the first factor, and within the second factor. Therefore, there are a total of six null hypotheses to test: three for the main effects and three for the interactions.
