What to review
Review recruitment, eligibility, fieldwork dates and exclusions. Ask whether the selection method leaves important groups with little chance of inclusion.
A practical example
A survey circulated only through a professional membership may miss workers outside that membership. A broad topic does not make the sample broadly representative.
Keep the claim in scope
Never infer a national or global population solely from the number of responses. The selection process matters.
Research and editorial context
A result is meaningful within its methodology. Match the research question, assessed universe and measurement period before making a comparison. These reference notes explain evaluation concepts; they do not add indicators, weights or thresholds to any published WCRC study.
Examples illustrate a decision and do not describe a named organisation's conduct. This is a reference note, not a new research finding or an award outcome.
