Question

The mean of the distribution is 22 and the standard deviation is 8. Then find the value of the coefficient of variation?
1. 28.43%
2. 41.41%
3. 33.33%
4. 36.36%

Answer 1

Correct Answer - Option 4 : 36.36%

Given:

The mean of distribution = 22

Standard deviation = 8

Formula used:

Coefficient of variation = [Standard deviation ÷ mean] × 100

Calculation

Standard deviation = 8

And mean distribution = 22

Coefficient variation = (8 ÷ 22) × 100

Coefficient variation = 36.36%
