Comprehensive Meta-Analysis

Comprehensive Meta-Analysis is a powerful computer program for meta-analysis. The program combines ease of use with a wide array of computational options and sophisticated graphics.

“CMA 2.0 is perhaps the most user-friendly statistical software I have used to date. It makes the complicated process of conducting a meta-analysis much easier. It can be used from start to finish - from direct data entry to publication-quality graphics. I highly recommend this program!”

Nathan Thoma, M.A., Psychology Intern, Payne Whitney Clinic, Weill Cornell Medical Center, New York - Presbyterian Hospital

“I found the Comprehensive Meta-Analysis software program to be extremely user friendly, providing instant computational data from the simplest to the most complex statistical problems, a versatile database to help organize and restructure large volumes of multifaceted data, and parallel visuals that help better understand your data.  I also found the support staff very helpful in providing responses to both my technical questions about the program itself as well as helpful addressing more general theoretical questions about meta-analyses.  I would highly recommend this program to a novice or more seasoned researcher interested in conducting meta-analytic statistics.”
