The coefficient of variation (CV) is defined as the ratio of the standard deviation $${\displaystyle \ \sigma }$$ to the mean $${\displaystyle \ \mu }$$, $${\displaystyle c_{\rm {v}}={\frac {\sigma }{\mu }}.}$$ It shows the extent of variability in relation to the mean of the population. The … See more In probability theory and statistics, the coefficient of variation (CV), also known as relative standard deviation (RSD), is a standardized measure of dispersion of a probability distribution or frequency distribution. … See more Advantages The coefficient of variation is useful because the standard deviation of data must always be understood in the context of the mean of the … See more The coefficient of variation is also common in applied probability fields such as renewal theory, queueing theory, and reliability theory. … See more • Omega ratio • Sampling (statistics) • Sharpe ratio • Variance function See more In the examples below, we will take the values given as randomly chosen from a larger population of values. • The data set [100, 100, 100] has constant values. Its See more When only a sample of data from a population is available, the population CV can be estimated using the ratio of the sample standard deviation $${\displaystyle s\,}$$ to the sample mean $${\displaystyle {\bar {x}}}$$: See more Comparing coefficients of variation between parameters using relative units can result in differences that may not be real.
