Review tiers 1–10

Checklists are parent-judged.
Written items: verify against practice set patterns.
Standard text: Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.

Practice test scoring
