Question

For a given distribution of marks mean is 35.16 and its standard deviation is 19.76. The co-efficient of variation is

• A. $\frac{35.16}{19.76}$
• B. $\frac{19.76}{35.16}$
• C. $\frac{35.16}{19.76} \times 100$
• D. $\frac{19.76}{35.16} \times 100$

Answer 1

Answer: (D)

$\frac{19.76}{35.16} \times 100$

Answer 2

Coefficient of variation $= \frac{\text{S.D.}}{\text{Mean}} \times 100\mathbf{=}\frac{\mathbf{19.76}}{\mathbf{35.16}}\mathbf{\times}\mathbf{100}$.
