## Overview

In the previous tutorials we looked at various applications of the linear model. We move on now to explore the concept of mediation. Perfect mediation occurs when the relationship between a predictor variable and an outcome variable can be completely explained by their relationships with a third variable. For example, taking a dog to work reduces work stress. This relationship would be mediated by positive mood if (1) having a dog at work increase positive mood; (2) positive mood reduces work stress; and (3) the relationship between having a dog at work and work stress is reduced to zero (or at least weakened) when positive mood is included in the model.
