WebIt's based on differences from the mean raised to the 4th power. So as events happen that are far from the mean, in either direction, it amplifies them dramatically. But much data in life is not independent or normally distributed, so high kurtosis doesn't necessarily correspond to your mental image of a fat tail. 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. A distribution with a high kurtosis is said to be "peaked", while a distribution with a low kurtosis is said to be "flat". diamond of stars in c++ https://paulwhyle.com
