Let $X \in \text{Random}(\mathbb{R})$ be a D3161: Random real number such that

(i)	$p \in (0, \infty)$ is a D5407: Positive real number
(ii)	$$\begin{equation} \mathbb{E} |X|^3 < \infty \end{equation}$$

The skewness of $X$ is the D993: Real number $$\begin{equation} \text{Skew} X : = \mathbb{E} [ (X - \mathbb{E} X)^3 ] \end{equation}$$
