Solution :-

Find the mean deviation from the median

Let us arrange the data in ascending order,

15.2, 27.9, 30.2, 32.5, 40.0, 52.3, 52.8, 55.2, 72.9, 79.0

We know that,

Where, |di| = |xi – M|

The number of observations are Even then Median 

= \(\dfrac{ (40+52.3)}{2}\) = 46.15

Median = 46.15

Number of observations, ‘n’ = 10

= \(\dfrac{1}{10}\) × 167.4

= 16.74

The Mean Deviation is 16.74.
