For those of you who are new to the topics of moderation and mediation, you may wish to gain a bit of background on these two topics by staying in this part of the web-site. I will describe a bit of the background on these topics, and then move on to give you an example of each method. Here is a general map of this web-site to help you move around:

Introduction
This web-site was created to help visitors with questions about moderation and mediation. In my teaching and research, I have found that:
1) moderation and mediation are increasingly used in state-of-the-art statistical analyses of data; and
2) statistics textbooks do not do a good job of explaining these two techniques. This leads to:
3) many students and even seasoned researchers to be very confused about when and how to use these approaches.

My goal in this web-site is to briefly describe the basics of each technique, and then provide you access to two on-line programmes that I think will be of significant assistance in the day-to-day utilization of moderation and mediation.
