Did you know?
WebThe coefficient of variation (CV) of a data set is defined as: CV = S / M where S is the standard deviation of the data set and M is its mean (average). The coefficient of variation can give us an idea of how the standard deviation compares to the mean: A CV of less than 1 means that the standard deviation is low. Web21 sep. 2024 · 1 Answer.
