Coefficient of Variation: The coefficient of variation measures the risk of an investment. It is calculated by dividing the standard deviation of returns by the expected value of returns. The coefficient of variation is most useful for comparing the risk of two or more investments with different expected returns. Answer and Explanation: 1

The Coefficient of Variation: The coefficient of variation is commonly used in econometrics (a branch of statistics), though you will likely encounter it in other contexts as well. It represents a simple ratio of the standard deviation to the mean of the data of interest. The coefficient of variation can be used to summarize data from a sample ...

Coefficient of Variation: The coefficient of variation is the percentage value that provides a variation measure: the relative measure of the standard deviation to the mean value of the data set. If the coefficient of variation for a series is large; the set is more scattered about the mean. small; the set is closer to the mean.
