Question

1. Find the coefficient of variation of 24, 26, 33, 37,29,31.
​

Answer 1

The coefficient of variation of 24, 26, 33, 37,29,31. is 14.4

Step-by-step explanation:

Data : 24, 26, 33, 37,29,31.

$Mean = \frac{\text{Sum of observations}}{\text{No. of observations}}$

$Mean = \frac{24+26+33+37+29+31}{6}$

$Mean = 30$

Standard deviation : $\sqrt{\frac{\sum(x_i-\mu)^2}{n}}$

Standard deviation : $\sqrt{\frac{(24-30)^2+(26-30)^2+(33-30)^2+(37-30)^2<strong>+</strong>(29-30)^2+(31-30)^2}{6}}$

Standard deviation : $4.32$

Formula of coefficient of variation : $CV =\frac{\sigma}{\mu} \times 100$

$CV =\frac{4.32}{30} \times 100$

$CV =14.4$

Hence the coefficient of variation of 24, 26, 33, 37,29,31. is 14.4
