Question 1

A police department tracks response times. The average response time is 8 minutes, but 20% of calls exceed 15 minutes. Which analytical action is most appropriate?

Accepted Answer

Investigate the causes of the 20% exceeding 15 minutes

Answer

A significant percentage of outliers signals a systemic issue that warrants investigation rather than statistical concealment.

Question 2

An investigator finds that a suspect's cell phone pinged a tower 2 miles from the crime scene at the time of the offense. What is the most accurate analytical statement about this evidence?

Accepted Answer

The ping is consistent with being near but not at the scene and should be weighed with other evidence

Answer

Cell tower pings indicate proximity within a range, not a precise location, so this evidence must be evaluated alongside other corroborating or contradicting information.

Question 3

A department's use-of-force incidents increased by 15% year-over-year. However, calls for service also increased by 20% in the same period. What does this data most accurately suggest?

Accepted Answer

The rate of use-of-force per call actually decreased

Answer

When calls increased 20% but use-of-force only 15%, the per-call rate of force actually declined, showing improvement relative to workload.

Question 4

During a traffic stop analysis, an officer finds that of 100 stops, 60 resulted in warnings and 40 in citations. Of the citations, 30 involved speeding. What fraction of all stops resulted in speeding citations?

Accepted Answer

30%

Answer

30 speeding citations out of 100 total stops equals 30%.

Question 5

An officer receives conflicting information: a victim states the assault occurred at 9 PM, but a store receipt places the suspect elsewhere at 8:55 PM. How should this discrepancy be handled analytically?

Accepted Answer

Document the discrepancy and seek additional corroborating evidence

Answer

Conflicting evidence requires additional investigation to resolve the discrepancy rather than automatically favoring one source.
