Types Of Kurtosis In Statistics. Kurtosis is measured by moments and is given by the following formula formula. The kurtosis of any univariate normal distribution is 3.
Rather it means the distribution produces fewer and less extreme outliers than does the normal distribution. In other words kurtosis identifies whether the tails of a given distribution contain extreme values. Kurtosis is a statistical measure that defines how heavily the tails of a distribution differ from the tails of a normal distribution.
Whenever the kurtosis is less.
Distributions with kurtosis less than 3 are said to be platykurtic although this does not imply the distribution is flat topped as is sometimes stated. The kurtosis of any univariate normal distribution is 3. Platykurtic distributions have negative excess kurtosis. What kurtosis tells us.
