Comprehensive Meta-Analysis
"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."
