About F-Distribution
The F-distribution is the ratio of two chi-square distributions divided by their respective degrees of freedom.
Properties:
- Always non-negative (F ≥ 0)
- Skewed to the right
- Shape depends on two parameters: df₁ and df₂
Common uses: ANOVA, comparing variances, regression analysis
Mean: df₂ / (df₂ - 2) for df₂ > 2
