Sxx Variance Formula

The Sxx variance formula is often used as an intermediate step to calculate the variance (σ²) and standard deviation (σ) of a dataset.

s2=Sxxn−1s squared equals the fraction with numerator cap S sub x x end-sub and denominator n minus 1 end-fraction For our example above ( Sxx Variance Formula

Variance (σ²) = E[(xi - μ)²]
