The lengths (in cm) of 10 rods in a shop are given below: 40.0,52.3,55.2,72.9,52.8,79.0,32.5,15.2,27.9,30.2 Find mean deviation from median (ii) find mean deviation from the mean also.

Explanation

`bar{x}` be the mean
`bar{x}=frac{40+52.3+55.2+72.9+52.8+79+32.5+15.2+27.9+30.2}{10}=45.98`

M D `=1/(10)**164.6=16.46`
