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. It is often expressed as a percentage, and is defined as the ratio of the standard deviation See more 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 … 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 … 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 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 standard deviation is 0 and average is 100, giving the coefficient of variation as 0 / 100 = 0 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 data. In contrast, the actual value of the CV is independent of the unit in which the … See more Comparing coefficients of variation between parameters using relative units can result in differences that may not be real. If we compare the same set of temperatures in Celsius and Fahrenheit (both relative units, where kelvin and Rankine scale are … See more WebOct 26, 2024 · By Jim Frost 30 Comments The coefficient of variation (CV) is a relative measure of variability that indicates the size of a standard deviation in relation to its …
