Teaching with PURR DataThis guide provides suggestions of datasets well suited to classroom use and student projects. It is intended to help you discover sample datasets, not to serve as a comprehensive introduction to data types and formats. All of the datasets listed here are free and publicly available for download in the Purdue University Research Repository (PURR). These are all "real" datasets generated by Purdue researchers, and, while useful in the classroom, were not created for educational purposes. The datasets presented here represent a variety of subjects and formats, and are relatively easy for students to understand and manipulate.
