WebKurtosis is a statistical measure that quantifies the degree of peakedness of a distribution. It is a measure of how often values in the distribution fall close to the mean, and how often they fall far away from the mean.

WebHowever, kurtosis is a measure that describes the shape of a distribution's tails in relation to its overall shape.
