About

QAC Projects is an online portfolio of data analysis projects conducted by students affiliated with the Wesleyan University Quantitative Analysis Center. The goal of the QAC Projects initiative is to promote a broader view of data analysis that encompasses topics such as data visualization, scalable computing, and the analysis of non-numeric data—topics which introductory statistics courses typically ignore, but which are increasingly important in both academia and industry.

If you are a student at Wesleyan interested in collaborating on QAC Projects, please contact us via email (qac@wesleyan.edu) or telephone ((860) 685–3795). We encourage all students to contact us, regardless of their background or major—an interest in data analysis is the only requirement.

Interested students may also find the source code for many of our projects available on the QAC Projects GitHub profile. We release all code under the BSD License and encourage pull requests.
