"Seeing that I can do with Comprehensive Meta‐analysis in 1 week what have taken me 3 weeks when I was using Excel spreadsheets for calculations I have the following: "Comprehensive Meta‐Analysis has increased my effectivity to do meta‐analysis with 200 %". I am extremely satisfied with this program."

"I have used Comprehensive Meta‐Analysis II for the last 6 years to assist with a number of published meta‐analytic studies in the behavioral sciences. I have found the program to be flexible and powerful. I have also used CMA II in two graduate seminars focused on meta‐analysis. The students are able to learn the program quickly and appreciate how it structures their data sets and prevents some common mistakes made in meta‐analysis."
