Question
Whenever a two-factor Analysis of Variance is performed, it is often the case that the main
summary ANOVA table tells us very little about the pattern of results obtained, and further
follow-up tests are required. The ANOVA summary table below is from a two-factor fully
between-subjects design. A and B on the table represent the main effects and AxB
represents the interaction.
Suggest follow-up test(s) in order fully to understand the patterns of significances
displayed. Explain your choice. If you believe that no follow-up tests are necessary,
then also explain why.
Assume that no planned comparisons are intended.
