    Task goals

    • Foundation: Identify basic features of a graph or report (title, axis labels, scale, source) and spot an obviously exaggerated or truncated axis.
    • Proficient: Explain how a specific choice, such as a non-zero baseline, inconsistent scale, or small sample size, could distort a reader's impression, and redraw or rewrite the item more fairly.
    • Excellence: Critique a complete statistical report (graph plus claim plus sample/source details), deciding whether the evidence actually justifies the stated conclusion and justifying that judgement in writing.
