In mathematics, the moments of a function are certain quantitative measures related to the shape of the function's graph. If the function represents mass density, then the zeroth moment is the total mass, the first moment (normalized by total mass) is the center of mass, and the second moment is the moment of inertia. … See more

For all k, the k-th raw moment of a population can be estimated using the k-th raw sample moment $${\displaystyle {\frac {1}{n}}\sum _{i=1}^{n}X_{i}^{k}}$$ applied to a sample X1, ..., Xn drawn from the population.
It can be shown … See moreThe first raw moment and the second and third unnormalized central moments are additive in the sense that if X and Y are independent random … See more

Let (M, d) be a metric space, and let B(M) be the Borel σ-algebra on M, the σ-algebra generated by the d-open subsets of M. (For technical reasons, it is also convenient to assume that M is a separable space with respect to the metric d.) Let 1 ≤ p ≤ ∞. See more

In works believed to stem from Ancient Greece, the concept of a moment is alluded to by the word ῥοπή (rhopḗ, lit. "inclination") and composites like ἰσόρροπα (isorropa, lit. "of equal inclinations"). The context of these works is mechanics and geometry involving the lever. In particular, in extant works attributed to Archimedes, the moment is pointed out in phrasings like:
