A property of a probability distribution. We distinguish between moments and central moments: * $n^{th}$ moment of $X= \mathbb E[X^n]$ * $n^{th}$ central moment of $X= \mathbb E[(X-\mu)^n]$ ^afe9bc **Prominent examples:** * [[Expectation]] is the first moment * [[Variance]] is the second central moment around $\mu$.
