you want to compare the variability of data sets that have very different means or units — you can put the consistency of a set of body weights next to a set of exam scores even if they share no units. This calculator uses the sample or population standard deviation you choose, divide it by the mean of the data and flags whether the relative variability is low, moderate or high (below about 15%, between 15% and 30%, or above 30% here). The CV is widely used in finance to compare investment risk per unit of return and in the lab to judge the precision of repeated measurements.The formula is simply CV = (standard deviation ÷ mean) × 100. This calculator uses the sample or population standard deviation.The CV is widely used in finance to compare investment risk per unit of return and in the lab to judge the precision of repeated measurements.Worked example: for 10, 12, 14, 16, 18 the mean is 14 and the sample standard deviation is about 3.16, so the coefficient of variation is 3.16 ÷ 14 × 100%The Worked example: for 10, 12, 14, 16, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73
