In this two-part video series Jarlath Quinn shows how to perform Moderation and Mediation analysis using the PROCESS macro developed by Andrew F. Hayes P.hD.
In Part 2 Jarlath looks at Mediation analysis. This is an analytical approach used to test if a third factor could represent the underlying cause of a relationship between an independent and dependent variable. For example, the relationship between wealth and educational success might be explained by the amount spent on private tuition. In such a situation, educational expenditure could act as a mediator variable and researchers could test to see if it did indeed explain the relationship.
