Formula and explanation
Formula: s = √((1)/(n - 1) ∑(i = 1)ⁿ (x i - x)²) Applicable Conditions: A set of observed data x₁, x₂,..., x n. Brief Description: The sample standard deviation is the square root of the sample variance. It has the same units as the original data, providing a more intuitive measure of data dispersion.
