##### Solution :-

To find the mean deviation from the mean, firstly let us calculate the mean.

By using the formula,

$$x= \dfrac{\displaystyle\sum f_ix_i}{f_i}$$

$$x= \dfrac{\displaystyle\sum f_ix_i}{f_i}$$

= $$\dfrac{350}{25}$$

= 14

$$x= \dfrac{\displaystyle\sum f_i|d_i|}{f_i}$$

$$\dfrac{158}{25}$$

= 6.32

The mean deviation is 6.32
