How Kurtosis Calculator works
Calculate population excess kurtosis m4 / m2² − 3.
Use 1–1,000 comma- or whitespace-separated numbers, each with magnitude at most 1 billion. Finite real inputs; output uses up to 12 significant digits. Floating-point results may be rounded. Requires at least two observations with nonzero variance. No finite-sample bias correction; a normal population has zero excess kurtosis. Finite real inputs; output uses up to 12 significant digits. Floating-point results may be rounded.
