📊 Survey Sampling in a Town: 2D Map and Estimators

Interactive 2D survey-sampling lab: a synthetic town of 1,200 people in 12 neighbourhoods and two groups. Compare simple random, stratified, cluster and convenience designs, watch confidence-interval coverage, bias, design effect and the power of a two-group test build up over hundreds of repeated surveys.
