Definition: Let $X$ be a random variable with expected value $\mu$ and standard deviation $\sigma$ and let $n$ be a positive integer. Then, the $n$-th standardized moment of $X$ is defined as the $n$-th moment of $X$ about the value $\mu$, divided by the $n$-th power of $\sigma$:
$$ \label{eq:mom-stand}
\mu_n^{*} = \frac{\mu_n}{\sigma^n} = \frac{\mathrm{E}[(X-\mu)^n]}{\sigma^n} ; .
$$
