|Table of Contents Univariate Data Distributions Most common distributons Poisson Distribution|
|See also: binomial distribution, relationship between distributions|
Similar to binomial distribution, but used if the probability that the observed event occurs is very small, in contrast to the population, that is a very large number.
|Applications||The Poisson distribution is the distribution of rare events. A typical application is the probability that a certain number of accidents will occur in a given interval, or the probability of radioactive decay. The number of atoms to decompose is relatively small compared to the number of all atoms in the material.|
