Mean Variance Standard Deviation. The Standard Deviation is. VarX Σx 2 p μ 2. Population variance is given by σ 2 sigma2 σ 2 pronounced sigma squared. The Mean Expected Value is.
Standard Deviation is a measure which shows how much variation such as spread dispersion spread from the mean exists. 22 15 35 8 10 In this example we will calculate the population standard deviation. It is a popular measure of variability because it returns to the original units of measure of the data set. It is a measure of dispersion of observation within dataset relative to their meanIt is square root of the variance and denoted by Sigma σ.
