Per-90 rates normalize for playing time but do not remove differences in role, team context or sample size. Show minutes and raw counts nearby. Decide whether playing time is the denominator that actually matches the question, rather than applying the rate by habit. Inspect a denominator example.

Include the reader, question, evidence, definitions, intended devices, interaction tasks, accessibility requirements and review responsibilities. Specify how a successful explanation will be judged. A list of preferred chart types is not a substitute for an analytical brief. Use the worksheet to organize a question.
