Run a regression analysis: Include the independent variable (X), the moderator variable (Z), and the interaction term (X*Z) as predictors of the dependent variable (Y). For example, if Z is a moderator for the relation between X and Y, we can fit a regression model: Y = β 0 + β 1 ∗ X + β 2 ∗ Z + β 3 ∗ X Z + ϵ Y = β 0 + β 2 ∗ Z + (β 1 + β 3 ∗ Z) ∗ X + ϵ Thus, if β 3 is not equal to 0, the We would like to show you a description here but the site won’t allow us. It is argued that given a theory-based, a priori hypothesis, an MMR analysis is analogous to a planned statistical comparison and, thus, a significant overall F value is not a prerequisite for interpreting a significant interaction term.
