Bus arrivals and bunching

Abstract

Finding suitable projects for introductory courses that blend real-world data with relevant questions and feasible instructor effort is often difficult. This paper describes one such project - tabulating the intervals between bus arrivals. By including data gathering, descriptive statistics, hypothesis tests, and regression, it covers most of the topics in a first course. This paper describes the genesis of the project, classroom implementation, analysis results for the student-generated dataset, and adaptations available for other classes and course sizes.
