Kurtosis Calculator: Measure Distribution Tailedness
Effortlessly calculate the kurtosis of a dataset to analyze the shape and tailedness of its distribution. Understand if your data is platykurtic, mesokurtic, or leptokurtic.
Kurtosis Result:
Kurtosis measures the "tailedness" of the probability distribution.
- Kurtosis ≈ 3 (Excess Kurtosis ≈ 0): Mesokurtic (similar to normal distribution).
- Kurtosis < 3 (Excess Kurtosis < 0): Platykurtic (flatter distribution with thinner tails).
- Kurtosis > 3 (Excess Kurtosis > 0): Leptokurtic (peaked distribution with fatter tails).
