What is the Coefficient of variation?

The coefficient of variation is the measure of relative variability. The coefficient of variation is the ratio of the standard deviation to the mean.

It’s very useful if we want to compare the results from the two different research or tests that consist of the two different results. For example, if we are comparing the results of two different matches that have two completely different scoring methods. Like if sample X has a CV of 15% and sample Y has a CV of 30%, it would be said that sample Y has more variation, relative to its mean. It helps us to provide Relatively simple and quick tools that help us to compare the data of different series.

Formula to calculate the coefficient of variation:

                                       Coefficient of Variation = (Standard Deviation / Mean) × 100

                                                           In symbols: CV = (SD/x̄) × 100

How to calculate Coefficient of Variation?

How to calculate the Coefficient of Variation? Statistics is the process by which the data is collected and analyzed. The coefficient of variation in statistics is explained as the ratio of the standard deviation to the arithmetic mean, for instance, the expression standard deviation is 15 % of the arithmetic mean is the coefficient variation.

This article provides the steps to calculate the coefficient of variation along with solved examples and practice problems.

How to calculate Coefficient of Variation in context to Finance

It helps us in the investment selection process that’s why it is important in terms of finance. In the financial matric, it shows us the risk-to-reward ratio means here the standard deviation/volatility shows the risk of the investment and mean is shown as the expected reward of the investment. The investors in the company identify the risk-to-reward ratio of each one of the security to develop an investment decision. In this, the low coefficient is not favourable when the average expected return is below the value of zero...
