Coefficient of M.D. $=\dfrac{\text{Mean deviation}}{\text{average used}}$ .

A relative measure of dispersion is formed by dividing the absolute measure by the corresponding average. For mean deviation taken about the mean,

$\text{Coefficient of M.D.}=\frac{\text{Mean deviation}}{\text{Mean}}.$

$Q. From the following the one which is a relative measure of dispersion is :$
(a) Range
(b) Quartile deviation
(c) Coefficient of mean deviation
(d) Standard deviation
›Reveal solutionSolution
Relative measures are ratios/coefficients; here that is the coefficient of mean deviation.

Measures of dispersion are of two kinds:

Absolute — expressed in the original units (Range, Quartile deviation, Mean deviation, Standard deviation).

Relative — a unit-free ratio obtained by dividing an absolute measure by an average (Coefficient of range, Coefficient of quartile deviation, Coefficient of mean deviation, Coefficient of variation). …

$Q. The mean deviation of 10, 12, 20 and 30, is :$
(a) $7$
(b) $18$
(c) $14$
(d) $6$
›Reveal solutionSolution

$\bar{x}=18$ , $\text{M.D.}=\frac{8+6+2+12}{4}=7$ .

Mean:

$\bar{x}=\frac{10+12+20+30}{4}=\frac{72}{4}=18.$

Absolute deviations from the mean:

$|10-18|=8,\;|12-18|=6,\;|20-18|=2,\;|30-18|=12.$
