Certified Internal Auditor (CIA) Part 2: Practice of Internal Auditing — Question 85

Which of the following attribute sampling methods would be most appropriate to use to measure the total misstatement posted to an accounts payable ledger?

Answer options

• A. Stop-or-go sampling.
• B. Probability-to-proportional size sampling.
• C. Classical variable sampling.
• D. Discovery sampling.

Correct answer: C

Explanation

Classical variable sampling is appropriate for estimating the total misstatement because it allows for the calculation of a point estimate and confidence interval, which is essential for assessing the accuracy of the accounts payable ledger. The other methods, like stop-or-go sampling and discovery sampling, are less effective for measuring total misstatements as they focus on identifying specific errors rather than providing a comprehensive estimate.
