Definition: Let $X$ be a random variable with expected value $\mu$ and standard deviation $\sigma$. Then, the skewness of $X$ is defined as the third standardized moment of $X$:
\[\label{eq:skew} \mathrm{Skew}(X) = \frac{\mathrm{E}[(X-\mu)^3]}{\sigma^3} \; .\]- Wikipedia (2023): "Skewness"; in: Wikipedia, the free encyclopedia, retrieved on 2023-04-20; URL: https://en.wikipedia.org/wiki/Skewness.
