ActivStats 3.0

ActivStats was designed and authored by Paul Velleman, and reflects modern research into how people learn, and specifically how people learn statistics.
Animated Activities introduce statistics concepts. Teaching Applets reinforce those concepts. Video is a motivational force, and guided analyses of real-world data provide hands-on practice with Data Desk. You'll get feedback from drag-and-drop quizzes, and return again and again to the glossary, index, and table of contents as ongoing sources of information.

ActivStats is used successfully by both professionals and students.
