Formula Explanation
Bowley's Coefficient of Skewness Formula
SK = (Q₃ + Q₁ - 2Q₂) / (Q₃ - Q₁)
Where:
- Q₁ = First Quartile (25th percentile)
- Q₂ = Median (50th percentile)
- Q₃ = Third Quartile (75th percentile)
- SK = 0: Symmetrical distribution
- SK > 0: Positively skewed (right-tailed)
- SK < 0: Negatively skewed (left-tailed)
