I note that SUM / 2 = Average.
So where is the Difference figure and why is it not recorded?
It is regarded as being rather important in Power and Signal work in other disciplines for good reasons.

This forms a small part of my research project/thesis proposal to Oxford so a funding grant request may be in order (I could probably do it through Kickstarter but Academia is a better place to put it). Any offers?
