Variance (σ²) = E[(xi - μ)²]

Master Sxx, and you master the variance — and a great deal of statistics beyond it. Sxx Variance Formula

Variance is expressed in (e.g., if your data is in meters, variance is in meters squared). To get back to the original units, you take the square root of the variance, which gives you the Standard Deviation ( ) . s=s2s equals the square root of s squared end-root Practical Applications Finance: Measuring the volatility of a stock's returns. Variance (σ²) = E[(xi - μ)²] Master Sxx,

Analysis of the cap S sub x x end-sub Formula in Statistical Variance and Regression cap S sub x x end-sub represents the corrected sum of squares for a variable s=s2s equals the square root of s squared

The formula cap S squared (or sometimes written as ) represents sample variance
