Detailed explanation-1: -In ANOVA, an interaction is defined as when the difference in the means of the response between the levels of one factor is NOT the same across all levels of another factor.
Detailed explanation-2: -The two-way ANOVA compares the mean differences between groups that have been split on two independent variables (called factors). The primary purpose of a two-way ANOVA is to understand if there is an interaction between the two independent variables on the dependent variable.
Detailed explanation-3: -Simple effects tests are follow-up tests when the interaction is significant. They explore the nature of the interaction by examining the difference between groups within one level of one of the independent variables.
