week 6 discussion QUAN

After reading the chapter written by Baron and Kenny as well as MacKinnon, what are the properties of mediator and moderator variables? What are the differences? Why is it important to be able to distinguish the differences? As part of your original post, please find one article in your area of interest that used a mediator or moderator model and provide a brief description of the article. Make sure to attach the original articles that you described. The article should have a method and results section. 

Note: Be sure to identify the IV, DV, and Mediator or Moderator in each article
