Calculate standard deviations and effect sizes

It's possible to specify the mean, standard deviation and number of subjects in the control group as well as the experimental group. As far as output parameters are concerned, the application reveals the pooled standard deviation, mean difference, Glass' Delta, Cohen's d, r (BESD - Binomial Effect Size Display), Hedge's unbiased d, standard deviation of unbiased d, along with the common language effect size.
Calculations can be made with one click while the results can be cleared just as effortlessly to start a new task. Unfortunately, there are no options implemented for copying, saving or printing all details. At most, you can select and copy text from individual fields.
