"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

"Comprehensive Meta‐Analysis v.2 is the definitive leading software for computing, presenting and analysing results of meta‐analyses. The programme provides beginners as well as advanced researchers meta‐analysis opportunities, unmatched by competing programmes. Computing effect sizes, combining across various types of outcomes, conducting moderators analyses, and presenting these rather complex analyses in less than five stages, could not have been more user‐friendly."
