How was the average response time by call priority calculated? The average response time is calculated by filtering calls for service received by the Hazel Crest Police Department in person, by 911, or by telephone that required a police response. The time each incident's first responding officer arrives on scene is determined, then subtracted from the time the call was originally logged. This difference gives the response time for each incident. The average response time by call priority is then obtained by grouping by call priority and calculating the median of these individual response times across all incidents.

How was the average time on scene by call priority calculated? The average time on scene is calculated by taking the time logged by officers when they arrive on scene and subtracting that from the time they mark themselves off the scene. The average time on scene by call priority is then obtained by grouping by call priority and calculating the median of the time on scene across incidents.
