Calculate sum of squares (SS) for variance and ANOVA analysis
About Sum of Squares
Sum of Squares (SS) measures the total variation in a dataset. It is fundamental to variance, standard deviation, and ANOVA calculations.
Formulas:
- SS Total: Σ(x - x̄)² or Σx² - (Σx)²/n
- SS Between (SSB): Σnᵢ(x̄ᵢ - x̄)²
- SS Within (SSW): ΣΣ(xᵢⱼ - x̄ᵢ)²
- Identity: SS Total = SSB + SSW
