The main purpose of finding coefficient of variance (often abbreviated as cv) is used to study of quality assurance by measuring the dispersion of the population data of a probability or frequency distribution, or by determining the content or quality of the sample data of substances. Coefficient of variation of one data set is lower than the coefficient of variation of other data set, then the data set with lower coefficient of variation is more consistent than the other. 1 2 meaning of the coefficient of variation. The main purpose of finding coefficient of variance (often abbreviated as cv) is used to study of quality assurance by measuring the dispersion of the population data of a probability or frequency distribution, or by determining the content or quality of the sample data of substances. In other words, a set of data is graphed and the cv equation is used to measure the variation in points from each other and the mean. The standard deviation of returns from an investment option is to be divided by the mean annual return of that option, to arrive at the coefficient of variation.

For the iq example, the variance = 14.4 2 = 207.36. In finance, the coefficient of variation is used to measure the risk per unit of return. For the iq example, the variance = 14.4 2 = 207.36. For example, if we have a standard deviation of 1.5 and a mean of 5, the ratio of the standard deviation to the mean is 0.3. It is similar to standard deviation since that is also used as a measure of risk but the difference is that the coefficient of variation is a better indicator of relative risk.
