Mean deviation from an average = MDX
⇒ MDX = 1/N(∑xi – A), A is average
⇒ Mean deviation from the median = MDmed
⇒ MDmed = 1/n(xi – Md)
Mean deviation about an arbituary point is minimum when the point is median
Coefficient of mean deviation = MDX/x̅, where x̅ is arithmetic meran
Coefficient of mean deviation based on MDmed/Md
∴ MDmed/Md = Minimum(MDx/x̅
