Mediators, Moderators, and Suppressors: What IS the difference?

by Karen Grace-Martin 2 Comments

One of the biggest questions I get is about the difference between mediators, moderators, and how they both differ from control variables.

I recently found a fabulous free video tutorial on the difference between mediators, moderators, and suppressor variables, by Jeremy Taylor at Stats Make Me Cry.   The witty example is about the different types of variables–talent, practice, etc.–that explain the relationship between having a guitar and making lots of $$.
