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 10, 2024 · Standard Deviation, σ = ∑ i = 1 n ( x i − x ¯) 2 n. In the above variance and standard deviation formula: xi = Data set values. x ¯. = Mean of the data. With the help of the variance and standard deviation formula given above, we can observe that variance is equal to the square of the standard deviation.
WebMar 11, 2024 · The standard deviation gives an idea of how close the entire set of data is to the average value. Data sets with a small standard deviation have tightly grouped, precise data.
