Certified Internal Auditor Research & Evidence-Based Practice 2 — Questions and Answers
Question 1: When an internal auditor uses meta-analysis to synthesize findings from multiple prior audits, the PRIMARY benefit is:
- Reducing the time required for fieldwork
- Identifying patterns and trends not visible in individual audits (Correct answer)
- Eliminating the need for professional judgment
- Satisfying regulatory reporting requirements
Correct answer: Identifying patterns and trends not visible in individual audits
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?
- Oral representations from management
- Externally generated documentation obtained directly by the auditor (Correct answer)
- Internal memos prepared by the auditee
- Auditor observations recorded in working papers
Correct answer: Externally generated documentation obtained directly by the auditor
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:
- 5% of transactions in the population are erroneous
- There is a 5% risk that the true population value falls outside the interval (Correct answer)
- The auditor is 95% certain that all errors have been detected
- The sample size represents 95% of the total population
Correct answer: There is a 5% risk that the true population value falls outside the interval
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:
- Are mandatory and subject to conformance assessment
- Provide recommended guidance that auditors must follow without exception
- Offer non-mandatory best-practice implementation advice (Correct answer)
- Supersede local regulatory requirements
Correct answer: Offer non-mandatory best-practice implementation advice
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:
- Statistical generalization to the full population is required
- Specific knowledge-holders relevant to the audit objective are targeted (Correct answer)
- Random representation of all employees is the goal
- Large sample sizes are available and needed
Correct answer: Specific knowledge-holders relevant to the audit objective are targeted
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.
Question 6: When an internal audit finding lacks sufficient evidential support, the MOST appropriate action is to:
- Issue the finding with a disclaimer
- Perform additional procedures to gather corroborating evidence (Correct answer)
- Rely on management's verbal confirmation
- Reduce the severity rating and include the finding anyway
Correct answer: Perform additional procedures to gather corroborating evidence
Audit findings must be supported by sufficient, reliable evidence; if evidence is lacking, the auditor must perform additional procedures before including the finding in the report.
Question 7: Which research methodology is MOST appropriate when an auditor wants to explore the root cause of a recurring control failure with no pre-existing hypothesis?
- Deductive quantitative analysis
- Exploratory qualitative case study (Correct answer)
- Confirmatory statistical testing
- Benchmarking against industry averages
Correct answer: Exploratory qualitative case study
Exploratory qualitative methods such as case studies are appropriate when the goal is to understand a phenomenon and generate hypotheses rather than test pre-defined ones.
