Question

Find the deviation from median for the data
$13,10,12,13,15,18,17,11,14,16,12$

Answer 1

Arranging is ascending order value of variable will be
$10,11,12,12,13,13,14,15,16,17,18$
Here n = 11
? Median (M) = Mean of values of 5th and 6th term
$M=\frac{13+13}{2}=\frac{26}{2}=13$
Mean deviation from median
$=\frac{\sum |x_1-M}{N}=\frac{22}{11}=2$
