When using a sample size calculator it is important to know what kind of inference one is looking to make: about the absolute or about the relative difference, often called percent effect, percentage effect, relative change, percent lift, etc. Where the fist is μ1 - μ the second is μ...

effect size. Instead, the effect size is calculated based upon the R2. G Power has a different setup--all input fields are in the same window and the effect size field is very obvious. Like other Power analysis programs, G Power can also draw a Power graph so that you can see the ...
effect size calculator tailored to the selected test. Example: For the two-group t-test users can, for instance, spec- ify the means µ 1 , µ 2 and the common standard deviation (s = s 1 = s 2 ) in the populations underlying the groups to cal- ...
Post-hoc Statistical Power Calculator for Hierarchical Multiple Regression This calculator will tell you the observed power for a hierarchical regression analysis; i.e., the observed power for a significance test of the addition of a set of independent variables B to the hierarchical model, over ...
