"CMA has been a huge asset in my research on motivation and self‐regulation. I have used this software to conduct multiple meta‐analyses, each requiring different and multiple formats of effect size. CMA surpassed my needs and expectations every time. The software is really "comprehensive" yet exceptionally user‐friendly. Fellows and students have learned to use it in just one sitting. I highly recommend CMA to any researcher wishing to conduct meta‐analysis in a highly effective and efficient manner."
