📊 Sampling Bias and Graph Matchups

Students analyze short Santa Ana data scenarios to decide which sampling method, graph type, and summary statistics best fit each question. Right after this mini-lesson, teams draft their own plan using a shared planning template that names data source or collection method, variables, cleaning steps, possible bias, and whether they will use a histogram, box plot, table, or scatter plot. In a structured critique round, each team gives feedback to 2 peers, receives feedback, and revises its plan before a quick teacher conference checks methodological fit.
