Variance is a vital statistical measure that quantifies the spread or dispersion of data points around their mean. By calculating variance, we gain insights into the variability within a dataset. The formulas provided facilitate the calculation of variance, whether for a sample or a population.
In mathematics, a permutation of a set is an arrangement of its members into a sequence. The word permutation also refers to the act of permuting (rearranging) objects.
Permutations are used in many different areas of mathematics, including combinatorics, probability theory, and graph theory. They are also used in many other fields, such as computer science, operations research, and statistics.
