Distribution Shape: Skewness & Kurtosis

Skewness (γ1\gamma_1): 0.0Symmetric (Zero Skew)
Negative SkewSymmetric (0)Positive Skew
Kurtosis (β2\beta_2): 3.0Mesokurtic (Normal)
Platykurtic (Flat)Mesokurtic (3)Leptokurtic (Peaked)

Statistical Moments

Skewness measures the asymmetry of the PDF around the mean. A positive skew has a tail extending towards more positive values.

Kurtosismeasures the "tailedness" of the distribution. Fatter tails and a sharper peak characterize high kurtosis (Leptokurtic).
