From the good ol' Librarians' Index to the Internet comes a good site/toolbox for learning and teaching stats.

"The Claremont Colleges' "Web Interface for Statistics Education" (WISE) seeks to expand teaching resources offered through Introductory Statistics courses, especially in the social sciences. This project aims to develop an on-line teaching tool to take advantage of the unique hypertextual and presentational benefits of the World Wide Web (WWW). This teaching tool's primary application is as a supplement to traditional teaching materials, addressing specific topics that instructors have difficulty in presenting using traditional classroom technologies. The tool serves to promote self-paced learning and to provide a means for advanced students to review concepts."
