The hypergeometric distribution is used for sampling without replacement. The density of this distribution with parameters m, n and k (named Np, N-Np, and n, respectively in the reference below) is given by. p(x) = choose(m, x) choose(n, k-x) / choose(m+n, k) for x = 0, â¦, k.
The frequency distribution graphs are frequency graphs and are used to define the characteristic which is more trust worthy than the tabulated form or other source. This frequency distribution graph helps us in finding the comparison between the continuous and discrete data.here are four types of frequency distributive graphs namely histogram, frequency polygon, frequency curves and ogive graph. Basically, aÃ¢ ogivea ogiveÃ¢ is a term that is used to describe the curves and. curved shapes
