Certified Information Systems Auditor (CISA) — Question 687

Which of the following analytical methods would be MOST useful when trying to identify groups with similar behavior or characteristics in a large population?

Answer options

• A. Deviation detection
• B. Cluster sampling
• C. Random sampling
• D. Classification

Correct answer: B

Explanation

Cluster sampling is ideal for identifying groups with similar behaviors or characteristics, as it focuses on dividing the population into clusters and analyzing those clusters. Deviation detection, random sampling, and classification do not specifically target the identification of homogeneous groups within a population, making them less suitable for this purpose.
