Power for a One-Sample Z-Test Applet

This exercise illustrates the relationship between statistical power (the probability of rejecting a false null hypothesis) and four features of the test situation: the size of the difference between the actual mean and the hypothesized mean; variability of scores within groups; sample size; and alpha error. A dynamic applet allows the user to manipulate a factor and immediately see the effect on other factors.
