DEFINITION of 'Mesokurtic'

A term used in a statistical context where the kurtosis of a distribution is similar, or identical, to the kurtosis of a normally distributed data set. Kurtosis is a measure of a distribution's peak, which means how much of the distribution is centered on the distributions mean.

The kurtosis coefficient of a normal distribution is 3.

BREAKING DOWN 'Mesokurtic'

Kurtosis is a measure of how extreme observations are in a data set. The greater the kurtosis coefficient, the more peaked the distribution around the mean is. Also, this distribution has fatter tails, which means there is an increase tail risk (extreme results).

When a distributions kurtosis coefficient is greater then 3, the distribution is leptokurtic, and when it's less then 3, its platykurtic.
