Question

If the mean is 25 and the standard deviation is 5 then the coefficient of variation is:
1. 48%
2. 60%
3. 20%
4. 27%

Answer 1

Correct Answer - Option 3 : 20%

Given:

Mean = 25

Standard deviation = 5

Formula used:

Coefficient of variation = Standard deviation/Mean × 100

Calculation:

According to the question

⇒ (5/25 × 100)  

⇒ 20%

∴ The coefficient of variation is 20%
