## Skewness and Kurtosis Formula

Skewness and kurtosis are statistical measures that describe the shape and distribution of a dataset.

### Skewness

Skewness measures the asymmetry of a distribution

skewness formula for data sample

g = Σ(Xi – x̄)³ / s * [n/(n-1)(n-2)]

• g = skewness
• Xi = individual observation
• x̄ = mean of dataset
• s = standard deviation
• n = Number of observations

### Kurtosis

Kurtosis measures the “tailedness” or the thickness of the tails of a distribution

Kurtosis formula for data sample

K = Σ(Xi – x̄)⁴ / s * [n(n+1)/(n-1)(n-2)(n-3)] – 3[(n-1)² / (n-2)(n-2)]

• k = kurtosis sample
• Xi = individual observation
• x̄ = mean of dataset
• s = standard deviation
• n = Number of observations
