CPI Data Analysis & Reporting 2 — Questions and Answers
Question 1: When analyzing financial records in a fraud investigation, which statistical method is most effective for detecting anomalies in large transaction datasets?
- Benford's Law analysis (Correct answer)
- Simple mean calculation
- Median absolute deviation only
- Standard deviation threshold
Correct answer: Benford's Law analysis
Benford's Law predicts the frequency distribution of leading digits in naturally occurring datasets and is widely used to flag manipulated financial records.
Question 2: A PI is preparing a final report for an attorney client. Which element is MOST critical to include for court admissibility purposes?
- Chain of custody documentation (Correct answer)
- The PI's personal opinion on guilt

Correct answer: Chain of custody documentation
Chain of custody documentation establishes that evidence was properly collected, handled, and preserved, making it admissible in legal proceedings.
Question 3: Which type of chart is BEST suited for showing the relationship between two continuous variables in an investigative data report?
- Scatter plot (Correct answer)
- Pie chart
- Gantt chart
- Histogram
Correct answer: Scatter plot
Scatter plots visually display correlations and patterns between two continuous variables, making them ideal for identifying relationships in investigative data.
Question 4: During a workers' compensation fraud investigation, a PI collects surveillance data over 30 days. What analysis technique best identifies behavioral patterns?
- Temporal pattern analysis (Correct answer)
- Random sampling
- Cross-tabulation of unrelated variables
- Single-day observation summary
Correct answer: Temporal pattern analysis
Temporal pattern analysis examines behavior across time intervals, revealing inconsistencies between claimed disabilities and observed activities.
Question 5: In a written investigative report, the executive summary should be placed:
- At the beginning, before the detailed findings (Correct answer)
- After all appendices
- In the middle of the report
- Only in verbal reports, not written ones
Correct answer: At the beginning, before the detailed findings
The executive summary appears at the beginning so clients can quickly grasp key findings without reading the full report.
Question 6: A PI discovers that a subject's cell phone records contradict witness statements. How should this discrepancy be addressed in the report?
- Present both sources objectively and note the contradiction without drawing conclusions (Correct answer)
- Discard the witness statements as unreliable
- Omit the contradiction to keep the report concise
- Accept the cell records as absolute truth and dismiss the witness
Correct answer: Present both sources objectively and note the contradiction without drawing conclusions
Objective reporting requires presenting all relevant evidence, including contradictions, and allowing the client or legal team to interpret the conflict.
Question 7: When using link analysis software to map relationships in an organized crime investigation, what does a node typically represent?
- An entity such as a person, phone number, or organization (Correct answer)
- A timeline event
- A financial transaction amount

Correct answer: An entity such as a person, phone number, or organization
In link analysis, nodes represent entities (people, organizations, accounts) while edges represent the relationships or connections between them.
