This paper describes how to incorporate data from a randomized controlled trial in rural Uganda into teaching an undergraduate business statistics course. The semester-length classroom exercise includes discussions and brainstorming sessions, which allow students to imagine how they would execute a field experiment and analyze the data. Students become familiar with one data set as they use it to supplement textbook examples of hypothesis testing, analysis of variance applications, and simple linear regression. The article discusses the background of the sustainability challenge of 2.8 billion people in the world cooking with solid fuels, the rollout and schedule of integrating field-experiment data into the classroom, and student evaluations of the exercise. The target audience is undergraduate statistics students and/or instructors interested in demonstrating how textbook statistics are used to better understand a real-world sustainability challenge.
