Technically it is a measure of volatility. Dispersion is the difference between the actual and the average value. The larger this dispersion or variability is, the higher is the standard deviation. Case to Consider WebbFormula: M D = 1 n ∑ i = 1 n x i-μ; Standard deviation: Standard Deviation is the measure of dispersion.
