Calculate the coefficient of variation from the following data:
Z-score = 1.32; standard deviation = 0.173; mean = 4.7; total variation = 0.6
A)27.16
B)156.66
C)0.04
D)-0.5

Question

Quizplus · Accepted Answer

The coefficient of variation is calculated as the ratio of standard deviation to mean, multiplied by 100 to express it as a percentage. 
Coefficient of Variation = (Standard Deviation / Mean) x 100
Given, Standard deviation = 0.173 and Mean = 4.7
So, Coefficient of Variation = (0.173 / 4.7) x 100 = 0.0368 x 100 = 3.68
Since the coefficient of variation is always expressed as a percentage, the answer should be rounded off to 2 decimal places, which is 3.68%
Therefore, the correct choice is C.
