Evaluate reports based on data.

Audit missing evidence with a structured checklist

Problem

A report says only, “\(70\%\) support.” Inventory the missing evidence needed to assess generalizability and precision.

Big Picture

What this problem is really about

A percentage is an estimate, not evidence that validates itself. To judge generalizability, inventory the target and frame, selection method, sample size, undercoverage, and nonresponse; to judge meaning and precision, ask for wording, response categories, study design, timing, uncertainty measure, confidence level, and method. Missing fields should remain explicit rather than being replaced by favorable assumptions.
