WebJan 30, 2024 · The coefficient of variation is calculated as the ratio of standard deviation to the absolute value of the mean. Hence, CV is always a positive number. This helps us determine if the standard deviation of data is small or … 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. Keywords
