Problem: mean deviation about median {85,96,76,108,85,80,100,85,70,95} [ Calculator, Method and examples ]

Solution:
Your problem -> mean deviation about median {85,96,76,108,85,80,100,85,70,95}

Median :
Observations in the ascending order are :
70, 76, 80, 85, 85, 85, 95, 96, 100, 108

Here, n=10 is even.

M=(text{Value of } (n/2)^(th) text{ observation} + text{Value of } (n/2 + 1)^(th) text{ observation})/2

=(text{Value of } (10/2)^(th) text{ observation} + text{Value of } (10/2 + 1)^(th) text{ observation})/2

=(text{Value of }5^(th) text{ observation} + text{Value of }6^(th) text{ observation})/2

=(85 + 85)/2

=85

 x |x - M| = |x - 85| 85 0 96 11 76 9 108 23 85 0 80 5 100 15 85 0 70 15 95 10 --- --- 880 88
