**Power Tutorial

http://wise.cgu.edu/powermod/index.asp

This tutorial is intended to teach students how power in a one-sample Z-test is influenced by effect size, variability (population standard deviation), sample size, and significance level. WISE Power Tutorial can be used in a variety of settings including as a tutorial for an individual student, during a lab, and after a lecture. The applet embedded in the tutorial could be used during an in-class demonstration.
