Certified Information Systems Auditor (CISA) — Question 884

In which of the following sampling methods is the entire sample considered to be irregular if a single error is found?

Answer options

• A. Discovery sampling
• B. Stop-or-go sampling
• C. Variable sampling
• D. Judgmental sampling

Correct answer: A

Explanation

Discovery sampling is designed to identify the presence of defects, and if any error is detected, the entire sample is deemed irregular. In contrast, Stop-or-go sampling and Variable sampling do not automatically classify a sample as defective based on a single error, as they involve different criteria for evaluation. Judgmental sampling is based on subjective criteria rather than strict error detection.
