The software is intended to be useful in planning statistical studies. It is not intended to be used for analysis of data that have already been collected.
Each menu selection provides a graphical interface for studying the power of one or more tests. The dialog windows include sliders (convertible to number-entry fields) for varying parameters, and a simple provision for graphing one variable against another. Each dialog window also offers a Help menu (on Macs, the Options and Help menus are added at the top of the screen). Please read the Help menus before contacting me with questions.
The “Balanced ANOVA” option provides another dialog with a list of several popular experimental designs, plus a provision for specifying your own model.
