Standard deviation distance
Measures of standard deviation distance
help explain the level and alignment of dis
persion in the crime data. These statistics
are best used as relative measures, com
paring crime types against each other or
the same crime types for different periods
of time. Exhibit 2 shows the standard devi
ation distances for the four crime types.
The greater the standard deviation dis
tance, the more dispersed are the crime
data. These results show that vehicle
crime is the most dispersed; robbery is
the least.
