WebIf we run two separate analyses, the control variables would also get different effects in the two models, and that might not be part of our theory. This is called an interaction analysis. It can also be called a moderation analysis, or that we are investigating conditional effects. WebThe presence of an interaction indicates that the effect of one predictor variable on the response variable is different at different values of the other predictor variable. Adding a term to the model in which the two predictor variables are multiplied tests this. The regression equation will look like this: Height = B0 + B1*Bacteria + B2*Sun ...
