I recognize that this not the mean. I was defining the term "Mean Radius" as used by army ordnance. The question was about 7.62 Match ammo as specified by Lake City.

After reviewing my statics reference:
Mean = Average.
Defined as the sum of the values of an event divided by then number of events.

Median is defined as: the value where the number of values above the median value is equal to the number of values below the median without regard to individual values.
In the series below,

19,14,10,-7-6,4,3
The median is Seven

If you had the individual values you could compute te standard deviation
IMHO
FWIW
