For this reason, you might often hear this type of analysis being referred to as a moderated multiple regression or as its abbreviation, MMR (e.g., Aguinis, 2004). We use the standard method of determining whether a moderating effect exists, which entails the addition of an (linear) interaction term in a multiple regression model. In this guide, we focus on (a) namely, the relationship between a continuous dependent variable and continuous independent variable, which is modified by a dichotomous moderator variable. This relationship is commonly between: (a) a continuous dependent variable and continuous independent variable, which is modified by a dichotomous moderator variable (b) a continuous dependent variable and continuous independent variable, which is modified by a polytomous moderator variable or (c) a continuous dependent variable and continuous independent variable, which is modified by a continuous moderator variable.
