WebIn statistic, the Coefficient of variation formula (CV), also known as relative standard deviation (RSD), is a standardized measure of the dispersion of a probability distribution … The coefficient of variation should be computed only for data measured on scales that have a meaningful zero ( ratio scale) and hence allow relative comparison of two measurements (i.e., division of one measurement by the other). The coefficient of variation may not have any meaning for data on an interval scale. [2] 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 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 … See more Comparing coefficients of variation between parameters using relative units can result in differences that may not be real. If we compare … 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 of variability in relation to the mean of the … 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 The coefficient of variation is also common in applied probability fields such as renewal theory, queueing theory, and reliability theory. In these fields, the exponential distribution See more
