Power Applet

Power Applet

These applets, presented by Virginia Tech's Department of Statistics, address the notion of "power." Users can perform one or two tailed tests for proportions or means for one or two samples. Set the parameters and drag the mouse across the graph to see how effect size affects power. Along with the applets, the site also contains test questions. This allows students to engage even more with the subject. This is a great resource for any mathematics classroom, especially when focusing on statistics.
