Coefficient of Variation - Meaning, Formula, Examples, Uses

WebDec 9, 2024 · Relative standard deviation, which also may be referred to as RSD or the coefficient of variation, is used to determine if the standard deviation of a set of data is small or large when compared to the mean. In other words, the relative standard deviation can tell you how precise the average of your results is. WebThe coefficient of variation (CV)is calculated as the standard deviation (SD) divided by the mean and multiplied by 100. CV indicates variability of the test results. This depends upon the test methodology, the instrument being used, and the range of results.
