Properties Of Binomial Distribution In Statistics. Binomial distribution is known as bi-parametric distribution as it is characterized by two parameters n and p. Normal distribution describes continuous data which have a symmetric distribution with a characteristic bell shape. Binomial distribution is a special case of Bernoulli distribution where the number of trial is up to n times instead of two times probability of success p and probability of failure q. There are only two possible outcomes on each trial- success and failure.
Probability of success p remains constant. Shape of the binomial distribution. Heads or tails and if any test is taken then there could be only two results. 1 it consists of a sequence of n identical trials. A binomial experiment has four properties. By the addition properties for independent random variables the mean and variance of the binomial distribution are equal to the sum of the means and variances of the n independent Z variables so These definitions are intuitively logical.
As it is classified by two parameters n and p.
The following examples describe the four properties of the binomial distribution and is inspired on Stuart Sidders youtube video. Thus it gives the probability of getting r events out of n trials. Binomial distribution describes the distribution of binary data from a finite sample. It is applied in coin tossing experiments sampling inspection plan genetic experiments and so on. Properties of a binomial distribution When an experiment has independent trails and each of them has two results that are success and failure. The probability of success p is the same for each outcome.
