Why is statistical sampling used in fraud audits?

• A. To efficiently test a population and identify potential misstatements without auditing every entry.
• B. To audit every single transaction for accuracy.
• C. To randomly discard data to simplify the audit.
• D. To lengthen the audit.

Answer: (A)

Statistical sampling is used because it lets auditors examine a manageable subset of transactions that represents the whole population, so they can assess whether there are misstatements or fraudulent activity without auditing every entry. In fraud audits, resources are limited and fraud can occur anywhere, so sampling provides a practical way to detect indicators of error or fraud with an estimate of how widespread they might be. By using a well-designed sample, the auditor can infer conclusions about the entire population with a known level of confidence and materiality. If the sample shows issues, investigators can focus their efforts where the risk appears higher, saving time and cost while still providing reasonable assurance. It isn’t about discarding data, auditing every transaction, or lengthening the audit.
