The only problem is that it is quite messy and tedious to find by hand! And as I have mentioned many times before: statisticians do not find these things by hand. They interpret the results from software or other calculators.
WebMar 9, 2024 · The coefficient of variation (relative standard deviation) is a statistical measure of the dispersion of data points around the mean. The metric is commonly used to compare the data dispersion between distinct series of data.
