Description:

Kurtosis, or fourth moment about the mean, is used to quantify the "peakedness" of data. A positive Kurtosis value indicates a sharp peak or node in the distribution. This is also referred to as leptokurtic. A negative Kurtosis value indicates a flattened or plateau-like distribution. This is also referred to as platykurtic.

Use:

Use to determine the "peakedness" of a distribution.

Press et al. (1992) recommend against the use of Kurtosis measurements in statistical evaluations.
