Find the mean, take absolute deviations of every value from it, and average those deviations.

Data: $3, 6, 10, 4, 9, 10$ ( $n=6$ ).

Mean:

$\bar x = \frac{3+6+10+4+9+10}{6} = \frac{42}{6} = 7$

Absolute deviations from the mean:

$x_i$	3	6	10	4	9	10
$\lvert x_i-\bar x\rvert$	4	1	3	3	2	3

Sum of absolute deviations $= 4+1+3+3+2+3 = 16$ . …
