Mediation models! At their core, mediation models explore the relations among three variables: A predictor, an outcome, and a secret third thing they call a Mediator. You’ve probably seen mediation models out there in the published literature, with folks testing paths, seeing if a relation is still there if a mediator is involved, or testing for an “indirect effect”. Jess and Sara talk about all of this in this episode. What is mediation, what kinds of questions can you ask with it, and why are people so mad about it? Jess and Sara go over the basics of this method, including a few examples, and talk a bit about the controversies surrounding it.
