Measures of central tendency
The Seattle police department looks for trends in its data to reduce crime. Specifically, they want to dispatch officers proactively when crimes are more likely to occur. In this exercise, you will identify patterns in the dates when crimes occurred. To do this, you'll use crime data from the first few days in January and the functions we discussed in the video.
Calculate summary statistics for the dates that crimes were committed using the AVERAGE()
, MEDIAN()
, MODE()
, and STDEV()
functions.
