While looking for an inexpensive technology package to help students in statistics classes, the author found StatKey, a free Web-based app. Not only is StatKey useful for students' year-end projects, but it is also valuable for helping students learn fundamental content such as the central limit theorem. Using StatKey, students can engage in interactive, simulation-based methods, creating a more authentic statistics experience. This article highlights StatKey's ability to aid instruction in sampling distributions, confidence intervals, and bootstrap confidence intervals. The author shares how students can use StatKey to build normal distributions and to study the behavior of sample statistics by generating many samples.
