PPAER Problem-Solving and Analytics 2 — Questions and Answers
Question 1: A patrol officer responds to 3 noise complaints on Oak Street within one week. Each complaint comes from a different neighbor about the same address. What is the most analytically sound conclusion?
- The neighbors are coordinating to harass the resident
- A recurring disturbance pattern likely exists at that address (Correct answer)
- Each complaint should be treated as an isolated incident
- The officer should dismiss the third complaint as redundant
Correct answer: A recurring disturbance pattern likely exists at that address
Multiple complaints from different sources about the same address within a short timeframe indicate a recurring pattern requiring further investigation.
Question 2: A dispatcher receives 12 calls in one hour. 4 are traffic accidents, 5 are medical emergencies, and 3 are property crimes. If medical emergencies always take priority, what percentage of calls require immediate priority response?
- 25%
- 33%
- 42% (Correct answer)
- 58%
Correct answer: 42%
5 medical emergencies out of 12 total calls equals approximately 42% (5/12 ≈ 0.4167).
Question 3: An officer notices that burglaries in a neighborhood spike every Friday and Saturday night between 10 PM and 2 AM. Which response strategy is most analytically justified?
- Increase patrols city-wide every night of the week
- Concentrate patrol resources in that neighborhood on Friday and Saturday nights (Correct answer)
- Interview all residents every Monday morning
- Install cameras at the police station
Correct answer: Concentrate patrol resources in that neighborhood on Friday and Saturday nights
Data showing a specific time and location pattern justifies concentrating resources precisely when and where crimes are most likely.
Question 4: A sergeant reviews incident reports and finds that Officer A files 20 reports per week while Officer B files 8. Officer A's district has 3 times the population of Officer B's. What is the most accurate analytical interpretation?
- Officer A is more productive than Officer B
- Officer B may be underreporting incidents relative to district activity (Correct answer)
- Officer A is writing unnecessary reports
- Population size is irrelevant to report volume
Correct answer: Officer B may be underreporting incidents relative to district activity
When adjusted for population (Officer A's 20 reports / 3x population vs Officer B's 8), Officer B's per-capita report rate is significantly lower, suggesting possible underreporting.
Question 5: During an investigation, a detective collects 6 witness statements. 4 place the suspect at Location A and 2 place him at Location B at the time of the crime. What should the detective conclude?
- The suspect was definitely at Location A
- The suspect was definitely at Location B
- Location A is more supported but both accounts require evaluation (Correct answer)
- The statements are too contradictory to use
Correct answer: Location A is more supported but both accounts require evaluation
A preponderance of statements supports Location A, but contradictory accounts require further corroboration rather than automatic dismissal of the minority view.
Question 6: A crime analyst maps 40 vehicle thefts over 6 months and finds that 32 occurred in parking lots with no lighting. Which conclusion best follows from this data?
- All parking lots are equally dangerous
- Poor lighting is a contributing risk factor for vehicle theft (Correct answer)
- Vehicle theft is caused solely by lighting conditions
- The 8 other thefts prove lighting is unimportant
Correct answer: Poor lighting is a contributing risk factor for vehicle theft
80% of thefts occurring in unlit lots indicates a strong correlation, making poor lighting a contributing risk factor worth addressing.
Question 7: An officer must prioritize three calls received simultaneously: a reported heart attack, a car alarm sounding, and a loud argument. Using standard triage logic, what is the correct order of priority?
- Car alarm, loud argument, heart attack
- Loud argument, heart attack, car alarm
- Heart attack, loud argument, car alarm (Correct answer)
- All three should be dispatched simultaneously with equal priority
Correct answer: Heart attack, loud argument, car alarm
Life-threatening emergencies (heart attack) take highest priority, followed by potentially escalating situations (argument), then property-related nuisances (car alarm).
