Evaluate reports based on data.
Why water teaches this standard well
Students critically evaluate a bottled-water company's report claiming tap water contamination, checking its sample size, sampling method, and framing for statistical soundness or bias. Evaluating a real, publicly circulated water report gives this standard immediate civic relevance.
Materials tagged with this code are written to the full standard , and each carries a written note explaining the alignment. See how we review materials.
