Abstract

This resource has been updated - find the current version here: https://qubeshub.org/qubesresources/publications/899


From the website:

This 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 selection provides a graphical interface for studying the power of one or more tests.  They 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" selection provides another dialog with a list of several popular experimental designs, plus a provision for specifying your own model.
