With support from the Mellon Foundation, my students and I developed and published a major web site in support of teaching of statistics: Web Interface for Statistics Education (WISE). The web site includes tutorials designed around interactive Java applets that demonstrate sampling distributions, the Central Limit Theorem, hypothesis testing, statistical power, and signal detection theory. The home page can be accessed at http://wise.cgu.edu .
