We present a case study to teach data visualization with Tableau in an introductory business analytics course. The case uses publicly available data sets from touringplans.com that record wait times for various attractions at Disney World in Orlando, Florida. In the case study, students use Tableau to clean, organize, and analyze wait time data, and to create data visualizations to illustrate how wait times are affected by several variables. Ultimately, students use their results to inform the client, a Disney travel agent, about when wait times are the shortest and longest. The case was piloted in a business analytics course; students reported finding the case study useful and interesting and were largely observed to meet the learning goals of the exercise.
