About Standard Deviation
Standard deviation is a measure of the amount of variation or dispersion in a dataset. It tells you how spread out the numbers are from the average (mean).
Formula
σ = √(Σ(x - μ)² / n)
Where:
• σ = Standard deviation
• x = Each value in the dataset
• μ = Mean of the dataset
• n = Numero of values
Interpretation
- • Low standard deviation = values are close to the mean
- • High standard deviation = values are spread out
- • Used in statistics, finance, and research
