Troubleshooting — Sampling

Sample size seems too large

  • Lower the confidence level (from 95% to 90%)
  • Increase the tolerable error rate
  • Check the population size is accurate
  • Consider whether judgmental sampling is more appropriate

Sample size seems too small

  • Increase the confidence level
  • Decrease the tolerable error rate
  • Verify the expected error rate is realistic

Can't generate random sample

  • Ensure the population data is loaded
  • Check that population size is correct
  • The random generator requires at least 1 item

Evaluation shows unacceptable results

  • The observed error rate exceeds the tolerable error rate
  • Options: expand the sample, investigate root cause, or report as a finding
  • Document the evaluation methodology and conclusion
