"I've been especially impressed by (1) the very wide range of effect size measures CMA accepts, and (2) how well it works with students learning about meta‐analysis. It's a wonderful resource!"

Geoff Cumming, DPhil - Emeritus Professor, School of Psychological Science, La Trobe University, Vic, Australia

"The distinguishing feature of the Comprehensive Meta‐Analysis Software Programme from the other Meta‐Analysis Software Programmes is to be most practical and to be understandable easily. While using the programme the only thing should be done is to enter the necessary data into the data sheet and to click on the relevant buttons. That's all. No need to calculate the statistical formulas by hand to reach the effect sizes, anymore. I would like to send my special thanks to you and your team from Ankara University, Ankara‐Turkey, Sevgi Guney, MSc in ClinPsych, MAPS"
