What if we want to look at relationships between more than 2 variables? Here, we introduce mediation and moderation, two of the most common (and useful) modeling techniques for assessing how more than 2 variables are related. We go over what they are used for, how to model them in R, and how to interpret their output.

The first workshop in a series of R modeling workshops. Here, we discuss hypothesis testing, and common group difference tests--t-tests and ANOVA.
