Question

find the mean deviation about the median for the data
13,17,16,14,11,13,10,16,11,1812,17
​

Answer 1

Answer:

Step-byThe given data is 13, 17, 16, 14, 11, 13, 10, 16, 11, 18, 12, 17

now, arrange it in ascending order,

10, 11, 11, 12 , 13, 13, 14, 16, 16, 17, 17, 18

now,

number of observation = 12 ( an even number )

so,

now, see in ascending order ,

6th position = 13

7th position = 14

hence,

M = ( 13 + 14)/2 =13.5

now ,

see attachment , we got absolute value of the deviation of xi from M.

now,

Mean deviation about median ,
