I have created two programmes which are designed to assist people computing mediation and/or moderation. Below are three links. The first one will take you to the introduction on these two statistical techniques as well as an example of each. The second and third links will take you to ModGraph or MedGraph, where you can actually use my programmes to assist you in making sense out of your data. Try them out. I hope that they will be of assistance to you. Write to me if you have further questions or problems with these programmes or documents.
