This project aims to develop curricular materials for a course that introduces students at the post-calculus level to statistical concepts, applications, and theory. This course provides a more balanced introduction to the discipline of statistics than the standard sequence in probability and mathematical statistics. The materials incorporate many features of successful statistics education projects that target less mathematically prepared students. The student audiences targeted by this project are particularly important because they have been overlooked by previous curricular reform projects. Most importantly, the proposed audience includes prospective teachers of statistics, introducing them to content and pedagogy that prepare them for implementing NCTM Standards with regard to statistics and probability and for teaching the Advanced Placement course in Statistics.

Course PrinciplesSome of the principles that have guided the development of these materials are:
Motivate with real studies and genuine data.
Emphasize connections among study design, inference technique, and scope of conclusion.
Conduct simulations often.
Use variety of computation tools.
Investigate mathematical underpinnings.
Introduce probability just in time.
Foster active explorations.
Experience the entire statistical process over and over again.
