Warde Mu Sigma Rho Statistics Education Award. In 2005, he received the CAUSEweb Resource of the Year Award and the Merlot Classics Award for the StatCrunch project. In 1997, he began to develop a complete online data analysis package called StatCrunch, which has blossomed into one of the most-used statistical resources on the web. To date, he has developed more than 50 such applets-many of which now accompany introductory statistics textbooks. West started to construct interactive web-based java applets that help students understand difficult statistical concepts. Shortly after completing his PhD in Statistics at Rice University in 1994, Webster West began developing Internet resources for statistical education.
