Welcome to DataFest 2026!

“The Unicorns” presenting their analysis during ASA DataFest 2025

Welcome to the official website of the annual ASA DataFest at Northwestern University! The event is hosted by the Department of Statistics and Data Science in collaborating with the ASA (American Statistical Association)

DataFest is an international competition organized by the American Statistical Association and hosted at universities across the world. Students are provided with a large dataset inspired by a real-world challenge and attempt to use their skills in data visualization, exploratory data analysis, and machine learning to propose a solution within 48 hours (over a weekend).

Students, operating in teams of 2-5, benefit from working alongside graduate students, professors, and industry professionals as expert mentors.

Event details

Date: Friday, April 24 at 5 pm - Sunday, April 26 at 7:30 pm

Students will be provided with a dataset and an open-ended goal on Friday evening. By Sunday afternoon, they will have to develop and present solutions to a panel of judges comprised of faculty and industry professionals. There will be prizes for first, second, and third place, and a people’s choice award. Teams will be evaluated on the quality of their recommendations, soundness of analysis, clarity of presentation, data visualization, use of external data, and overall creativity. Graduate students and industry professionals will be mentoring student teams as they develop their solution.

The event also includes a keynote speech from a leading industry expert, and a panel discussion on Careers in data science comprising of both faculty and industry professionals.
