1)

The mean deviation from the median of the data 16,22,3,14,5,10,8,6,11,4 is 


A) 5

B) 5.7

C) 4.7

D) 4

Answer:

Option C

Explanation:

Given  data,

16,22,3,14,5,10,8,6,11,4

 rranging is ascending order 

  3,4,5,6,8,10,11,14,16,22

 Median= (5th+6th )  observation/ 2= $\frac{8+10}{2}=9$

 Mean deviation from the median

=$\frac{ |3-9|+|4-9|+|5-9|+|6-9|+|8-9|+|10-9|+|11-9|+|14-9|+|16-9|-|22-9|}{10}$

 = $\frac{6+5+4+3+1+1+2+5+7+13}{10}$

   =$\frac{47}{10}=4.7$
