It will also calculate the standard t-test. The larger the sample required to detect a significant difference. The formula for effect size is quite simple and it can be derived for two populations by computing the difference between the means of the two populations and dividing the mean difference by the standard deviation based on either or both the populations.
If you enter the mean number of values and standard deviation for the two groups being compared it will calculate the Effect Size for the difference between them and show this difference and its confidence interval on a graph.
The outcome or result of anything is an effect. D and r Y l are positive if the mean difference is in the predicted direction. Calculate the mean SD and n. It runs in version 5 or later including Office95.
