Testing Analyst Candidates

The written exam for a crime analyst position helps determine which candidates possess the necessary or desired knowledge and skills for the position.  The written exam should cover the various duties that the analyst will be expected to perform.  Each of the following sections tests the knowledge of the applicant to perform the duties of a crime analyst.

Statistics

An analyst needs to have at least a minimum level of knowledge with statistics to measure the performance of the agency and compare rates of crime.  This section provides examples of questions that can be used to determine the level of knowledge that the candidate possesses to perform the statistical duties of an analyst.

 

Given a set of numbers, what is the mean, median, and mode?

  • Sample: 9, 4, 2, 5, 7, 4, 2, 3, 4, 3, 4, 8, 6, 7, 8
    • Mean = 5.067
    • Median = 4
    • Mode = 4

Provide a set of crime statistics for a multi-year timeframe.  Have the applicant determine the percentage change for certain crimes within a certain timeframe.  Below are sample data and questions that can be included in this section.

 

Stats

  • What is the percentage change in Robbery between 2008 and 2009?
    • -23%
  • What is the percentage change in Residential Burglary between the last 6 months of 2008 and the last 6 months of 2009?
    • 42.5%

  • Analyze the Robbery crime category and discuss what you see.  What inferences can be made from the data?
    • Robbery cases should be reviewed to determine what types of robberies are happening (bank, street, convenience stores, etc.) in order to see if there is an increase in one specific sub-type that is accounting for the overall rise. 
    • Possible theory - Increase in Robbery in Nov. and Dec. of 2008 may be due to the holiday season.  More people walking around with gifts and money provide more targets for offenders.
    • Possible theory - A known offender may have been released from custody in the fall of 2008 and/or arrested in early 2009 accounting for spike in Robberies in between.

    • Auto Theft: 140, Population: 200,000
      • Answer: 70
    • Assault: 114, Population: 250,000
      • Answer: 45.6

Practical Exercises

    To test the candidate’s skill level in Excel, have him/her produce a chart based on crime statistics.  Provide the candidate a spreadsheet of crime statistics for a one or two year period and ask them to produce a chart that compares certain crime types within a certain timeframe.

     

    Provide a scenario (incident reports or narrative describing a crime series) and have the applicant perform analysis on the information provided.  The information should include a crime trend, pattern, or some commonality that gives the candidate the opportunity to show how they would relate the incidents (and not relate ones that don’t have aspects in common).

     

    Candidate work products could include a crime matrix, summary analysis narrative, or crime bulletin.

     

    Forecasting – given a set of dates/times, have the candidate predict when the next crime in a series is likely to occur.
