WebMar 3, 2024 · The coefficient of variation simply expresses the standard deviation as a fraction of the mean value, and is best applied to ratio-scale data that has a meaningful zero value. A low CV indicates that the distribution is narrow about the mean, while a high CV indicates that the distribution has more variability about the mean. WebThe coefficient of variation (CV) is a statistical measure used to assess the variability of a set of data relative to its mean. ... The CV is calculated by dividing the standard deviation of the data by its mean and multiplying the result by 100. A lower CV indicates that the data is more consistent, while a higher CV suggests greater variability.
WebThe coefficient of variation can be plotted as a graph to compare data. A CV exceeding say about 30 percent is often indicative of problems in the data or that the experiment is out of control. Variates with a mean less than unity also provide spurious results and the coefficient of variation will be very large and often meaningless.
