🗺️ Evidence Exchange Walkthrough

Teams set up their interactive poster board with the city map, tables, histograms, box plots, scatter plots, sticky-note prompts, and one-page policy brief, then deliver a one-minute action plan talk during a gallery-style walkthrough. Classmates, staff, and the nonprofit partner circulate, ask questions about what the numbers reveal or hide, and vote on the most realistic action plan. Midway through the event, each team completes a brief partner feedback exchange with the community organization, then turns in a 3-4 sentence revision note naming one change made for realism or relevance and the evidence behind it.
