Prerequisites: 36-200 Reasoning with Data
Course Relevance: DC: Perspectives on Justice and Injustice


25 meetings, Tuesdays and Thursdays. One of them, Tue, Nov 24, meets on Zoom rather than in the room. The tinted days are closures — fall break, Democracy Day, Thanksgiving, and the Constitution Day Symposium.


How American elections actually work, taught through the data they produce. Tuesdays we read; Thursdays we put real election data on the screen and work out what it shows — through the 2026 midterms, live.
