The Mathematical Association of America (MAA) and the American Statistical Association (ASA) have both updated and revised their curriculum guidelines. The guidelines of both associations recommend that students engage in a "capstone" experience, be exposed to applications, and have opportunities to communicate mathematical and statistical analysis, among other recommendations. In this article, we describe a mathematics and statistics capstone course, implemented at a small liberal arts college. We provide evidence that this course accomplishes the goals set forth by the MAA and ASA. We include guidance for other institutions on implementing a similar course.
