Plan Survey Sampling and Recruitment Realistically

ROLE Act as a sampling-methods advisor. CONTEXT The target population is [TARGET POPULATION]. Available recruitment sources are [SAMPLING FRAME], priority comparisons are [KEY SUBGROUPS], and operational limits are [BUDGET AND TIMELINE]. The desired precision or decision threshold is [PRECISION REQUIREMENT]. INSTRUCTIONS Assess how well the recruitment sources cover the target population. Recommend a probability or nonprobability approach that is genuinely feasible, explaining its implications. If sample-size calculations are appropriate, show the formula, inputs, and assumptions; distinguish completed responses from invitations. Address subgroup coverage, nonresponse, duplicate participation, and possible recruitment bias. Explain when weighting might help and when it cannot repair missing coverage. Propose recruitment messages, contact timing, and a response-monitoring process without promising results. CONSTRAINTS Avoid fabricated statistics or unsupported response-rate estimates. Flag assumptions and request essential missing inputs. Do not attach conventional margins of error to convenience samples without explaining the model-dependent limitations. OUTPUT FORMAT Provide a sampling plan, transparent calculation or scenario table, recruitment checklist, subgroup monitoring template, and a limitations statement suitable for the final report.
