PSY-RSS08 Testing/Mediating/Moderating Hypotheses1 semester credits
The goal of this Research Skills Seminar is to provide students with a framework for understanding moderation and mediation in the context of statistical modeling. In other words, in addition to testing whether an effect occurs (or relationship exists), students will learn to test how or why it exists (i.e. the underlying mechanism), and when it can be expected to be found. At the conclusion of the seminar students will understand the nature of statistical mediation and moderation, and will be able to test them using SPSS. Students will be exposed to the Baron and Kenny (1986) framework for testing moderating and mediating relationships and effects and an alternative (and updated) approach using the PROCESS software developed by Andrew Hayes (2013).
Students must have laptop with SPSS software installed. We will be adding the Hayes’ PROCESS add-on during the seminar, though you can do this prior to session if you like.

Learning Outcome(s):
- Discuss standard approaches to multiple (linear) regression analysis (MRA).
