Skewness and kurtosis — asymmetry and tail weight — and what they break in the Gaussian assumptions behind most tests.
In Statistics, the concept of the shape of a Probability distribution arises in questions of finding an appropriate distribution to use to model the statistical properties of a population, given a sample from that population. The shape of a distribution may be considered either descriptively, using terms such as “J-shaped”, or numerically, using quantitative measures such as skewness and kurtosis.
