"Comprehensive meta‐analysis (CMA) is essential software for the meta‐analyst. Complex analyses can be conducted easily using this intuitive software. The support staff are always helpful and respond quickly when questions arise. I highly recommend CMA."

Erika A. Patall - Department of Educational Psychology, The University of Texas at Austin, Austin, TX

"Comprehensive Meta‐Analysis is the premier program for conducting meta‐ analyses. It has incredible flexibility in including many different types of effect sizes and in converting between them in a single analysis. It is extremely user‐friendly and has brilliant graphical capabilities."
