Standard deviation is a measure of how spread out numbers are from their average value. It’s widely used in various fields, including finance, science, and social sciences, to quantify the amount of variation or dispersion of a set of data values.
The formula for standard deviation differs slightly depending on whether you’re working with a sample or a population:
s = √[Σ(x - x̄)² / (n-1)]
σ = √[Σ(x - μ)² / N]
Where:
