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...

The coefficient of variation CV describes the standard deviation as a percent of the mean. Because it has no units, you can use the coefficient of variation to compare data with different units. Find the coefficient of variation for each sample data set. What can you conclude?

Integrative-Expected return, standard deviation, and coefficient of variation An asset is currently being considered by Perth Industries. The probability distribution of expected returns for this asset is shown in the following table, EEB a. Calculate the expected value of return, r, for the asset. b. Calculate the standard deviation, σ, for the asset's returns c. Calculate the coefficient of variation, CV, for the asset's returns a. The expected value of return, r, for the asset is 13%.
