Power of a Hypothesis Test Applet
This simple applet from Todd Ogden of the University of South Carolina allows you to compute power for a given True Mean, Hypothesized Mean, Sigma, and N. Students can explore how the power changes by varying different parameters. (You must input these parameters in the given text boxes before the graph will appear!)
