About Skewness
Skewness measures the asymmetry of a probability distribution. A distribution can be:
- Positively skewed (right-skewed): Tail extends to the right, mean > median
- Negatively skewed (left-skewed): Tail extends to the left, mean < median
- Symmetric: Skewness ≈ 0, mean ≈ median
Interpretation Guidelines:
- |skewness| < 0.5: Approximately symmetric
- 0.5 < |skewness| < 1: Moderately skewed
- |skewness| > 1: Highly skewed
