[TowerTalk] My Yearly Mistake

[Roger (K8RI) on TT]

Agreed.  When looking at a specific demographic, of comparing given 
attributes between differing demographics.  In ham radio, there are the 
different groups by mode and purpose.
RFI is a good one as there are so many sources, with differing 
approaches for solving the problems.

The median is useful for a lot of sociological data as the question often asked is "what is typical for a single data point".  For populations that are additive in nature (say, rainfall amounts), the average is probably more useful if for no other reason than you can multiply it by the number of samples and get the total for the dataset.
