With the availability of very large data sets, Data Mining has become an important quantitative skill to have in business and other fields. Bryant's program was successfully completed by 22 undergraduate students last year. This paper provides a description of Bryant's program along with the history of how the program was started and how it has grown. We discuss the curriculum, teaching materials, the SAS collaboration and some of the challenges which have been encountered.展开更多
