The Penrose method (or square-root method) is a method devised in 1946 by Professor Lionel Penrose [1] for allocating the voting weights of delegations (possibly a single representative) in decision-making bodies proportional to the square root of the population represented by this delegation.

Each uses one of a variety of methods of allocating seats – the D'Hondt method, the Sainte-Laguë method or a different one. Through the late 1800s and early 1900s, political reformers were involved in discussion and squabbles on the alternative system that would replace the first-past-the-post or block voting systems that were being used.

In probability theory and statistics, the beta distribution is a family of continuous probability distributions defined on the interval [0, 1] or (0, 1) in terms of two positive parameters, denoted by alpha (α) and beta (β), that appear as exponents of the variable and its complement to 1, respectively, and control the shape of the distribution.
There are many ways of calculating confidence intervals, and the best method depends on the situation. Two widely applicable methods are bootstrapping and the central limit theorem . [ 15 ] The latter method works only if the sample is large, since it entails calculating the sample mean X ¯ n {\displaystyle {\bar {X}}_{n}} and sample standard ...
The following binary search tree (BST) corresponds to each execution of quicksort: the initial pivot is the root node; the pivot of the left half is the root of the left subtree, the pivot of the right half is the root of the right subtree, and so on. The number of comparisons of the execution of quicksort equals the number of comparisons ...
The Pareto principle may apply to fundraising, i.e. 20% of the donors contributing towards 80% of the total. The Pareto principle (also known as the 80/20 rule, the law of the vital few and the principle of factor sparsity [1] [2]) states that for many outcomes, roughly 80% of consequences come from 20% of causes (the "vital few").
