Kurtosis Calculator
Calculate kurtosis to measure the tail heaviness of your data distribution
About Kurtosis
Kurtosis measures the "tailedness" of a probability distribution - whether data has heavy or light tails compared to a normal distribution.
Types:
- Leptokurtic (kurtosis > 0): Heavy tails, more extreme values, sharper peak
- Mesokurtic (kurtosis ≈ 0): Similar to normal distribution
- Platykurtic (kurtosis < 0): Light tails, fewer extreme values, flatter peak
Note: Excess kurtosis subtracts 3 from raw kurtosis, so a normal distribution has excess kurtosis of 0.
