Certified Internal Auditor Research & Evidence-Based Practice 2

Question 1

When an internal auditor uses meta-analysis to synthesize findings from multiple prior audits, the PRIMARY benefit is:

Accepted Answer

Identifying patterns and trends not visible in individual audits

Answer

Meta-analysis aggregates results across multiple studies or audits to reveal overarching patterns and trends that single audits cannot detect.

Question 2

Which type of evidence is considered MOST persuasive when evaluating internal control effectiveness?

Accepted Answer

Externally generated documentation obtained directly by the auditor

Answer

Externally generated evidence obtained directly by the auditor is most persuasive because it is independent of the auditee and obtained through the auditor's own procedures.

Question 3

An auditor applies a 95% confidence interval to sampling results. This means:

Accepted Answer

There is a 5% risk that the true population value falls outside the interval

Answer

A 95% confidence interval means there is a 5% risk (alpha risk) that the true population parameter lies outside the calculated interval.

Question 4

The IIA's Practice Guides differ from Standards in that Practice Guides:

Accepted Answer

Offer non-mandatory best-practice implementation advice

Answer

Practice Guides are strongly recommended but non-mandatory guidance that helps auditors implement the Standards in specific situations.

Question 5

A researcher uses purposive sampling to select interview subjects for an audit. This approach is BEST suited when:

Accepted Answer

Specific knowledge-holders relevant to the audit objective are targeted

Answer

Purposive sampling deliberately selects subjects based on specific characteristics or knowledge relevant to the research question, making it ideal when expertise matters more than statistical representation.
