✍️ Sample ADA Questions & Answers
1. When presenting the results of a complex audit data analytic to the company's audit committee, which communication principle is MOST important for the auditor to follow?
The audit committee's role is strategic oversight. They need a clear, concise summary of the most significant findings and the associated business risks, not the granular technical details. Effective communication for this audience translates complex data into business impact and actionable insights.
2. Which of the following questions is best answered using descriptive analytical techniques?
Descriptive analytics focuses on summarizing historical data to answer the question 'What happened?'. Calculating the total of overdue accounts receivable is a direct summary of past events. The other questions relate to diagnostic ('why'), predictive ('what is the probability'), and prescriptive ('what is optimal') analytics, respectively.
3. In hypothesis testing for audit analytics, what does a p-value of 0.03 indicate when the significance level is 0.05?
Since 0.03 < 0.05, the result is statistically significant and the auditor rejects the null hypothesis.
4. When an auditor identifies a statistically significant outlier in transaction data, the most appropriate next step is to:
Outliers warrant follow-up investigation to understand root cause before reaching a conclusion about their nature.
5. What does 'round dollar' analysis in fraud detection examine?
Round dollar analysis identifies an abnormal frequency of transactions with even dollar amounts such as $1,000 or $5,000, which may indicate fabricated or estimated transactions rather than legitimate arm's-length transactions.
6. Which data analytics test is most effective for detecting fictitious vendors in accounts payable?
Matching vendor master file data against employee records can reveal fictitious vendors created by employees, who often accidentally use their own contact information or banking details for the fake vendor.
