it tends to diminish multicollinearity, especially between the interaction effect and its constituent main effects; it may render ourb-coefficientsmore easily interpretable. We'll cover an entire regression analysis with a moderation interaction in a subsequent tutorial. For now, we'll focus onhow t...

When both explanatory variables and moderating variables are continuous variables, hierarchical regression analysis is done to test the moderating effect (Wen et al. 2005). Likert scale values are not continuous, but can be analyzed using hierarchical regression as they were (Johnson and Creech, 1983...
