Webb19 nov. 2024 · Briefly, skewness is a measure of symmetry. To be exact, it is a measure of lack of symmetry. This means that the larger the number is the more your data lack symmetry (not normal, that is). Kurtosis, on the other hand, is a measure of whether your data is heavy- or light-tailed relative to a normal distribution.
