Calculate the mean deviation about median of the following data.(i) 34, 66, 30, 38, 44, 50, 40, 60, 42, 51

Explanation

Arrange the numbers in
Ascending orders we get `30,34,38,40,48,44,50,51,60,66`

Here the number of observation are Even

then the middle terms are 42,44...

Therefore, the median
`=(42+44)/2​​`

`=43`


Mean deviation
=`∣d_i∣`=`∣` xi`−43∣` `=(13+9+5+3+1+1+7+8+17+23)/(10)`

`=(87)/(10)`
