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".

The kurtosis is the fourth standardized moment, defined as where μ4 is the fourth central moment and σ is the standard deviation. Several letters are used in the literature to denote the kurtosis. A very common choice is κ, which is fine as long as it is clear that it does not refer to a cumulant. Other choices include γ2, to be similar to the notation for skewness, although sometimes this is instead reserved for the excess kurtosis.
