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

Coefficient of Variation (CV) = (Standard Deviation / Mean) x 100%
CV = (0.173 / 4.7) x 100% = 0.0368 x 100% = 3.68%
Since the CV is a percentage, the correct answer must be a positive value. Therefore, options A, B, and D can be eliminated. Option C is the correct answer.
