ABOUT THIS EPISODE
What can we say about the often used and often confused statistical approach that is moderation? Quite a lot actually. In this episode Jess and Sara introduce the basics of moderation (aka statistical interactions) using absolutely no math (or very nearly absolutely no math). Listen to get a primer on the kinds of questions you can ask with moderation, and to get answers to common moderation questions like: Why is my interaction negative if my main effect is positive? Can I interpret the man effect if the interaction is significant? Why is my interaction significant if my main effect isn’t? And how do I graph the result when I have continuous variables?
