Answer to the question is option A. It is unitless , allowing the comparison of different variables.
Its unit less feature is what separates it from a standard deviation analysis.
Add Answer to:
What is the primary advantage of the coefficient of variation? O A. It is unitless, allowing...

Standard deviation versus coefficient of variation as measures of risk Greengage, Inc., a successful nursery, is considering several expansion projects. All of the alternatives promise to produce an acceptable return. Data on four possible projects appear in the following table ! a. Which project is least risky, judging on the basis of range? Data Table b. Which project has the lowest standard deviation? Explain why standard deviation may not be an entirely appropriate measure of risk for purposes of this...

Coefficient of Variation The coefficient of variation standardizes a variable's dispersion (standard deviation) relative to its mean. Imagine two variables, each with a standard deviation of 20. If Variable 1 has a mean of 100 and Variable 2 has a mean of 10, it is obvious that has more relative uncertainty. The coefficient of variation, the amount of risk per unit of the mean, is found by dividing the standard deviation by the mean, as follows: CV = Standard Deviation...

QUESTION 01 (10 points) - Coefficient of Variation (CV) We need to compare volatility of multiple assets. As the assets have different variation ranges, e.g. a big stock versus a penny stock, it is useful to look at the coefficient of variation, not the standard deviation, as a measure of volatility. We have the following population data: Asset A Asset B Asset C Mean ($) 0.45 183.94 305.81 Standard deviation ($) 0.11 29.56 61.35 (a) [2] Give an equation for...
