WebMar 9, 2024 · Updated March 9, 2024 What is the Coefficient of Variation? 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. WebApr 28, 2024 · Standard deviation is important because it measures the dispersion of data – or, in practical terms, volatility. It indicates how far from the average the data spreads. This helps you determine the limitations and risks inherent in decisions based on that data.
