WitrynaThis calculator uses a variety of equations to calculate the statistical power of a study after the study has been conducted. 1. "Power" is the ability of a trial to detect a difference between two different groups. If a trial has inadequate power, it may not be able to detect a difference even though a difference truly exists. the w georgia
