In my last post I discussed the binomial distribution and that article can be read here:- https://tracyrenee61.medium.com/create-a-binomial-distribution-and-test-it-in-excel-with-python-5f03c40aaa8c
In this post I intend to discuss the Poisson distribution and how to test it.
The Poisson distribution is one of the most popular distributions in statistics. In order to understand the Poisson distribution, it is necessary to understand Poisson experiments, which have the following properties:-
- The number of successes in the experiment can be counted.
- The mean number of successes that can be counted in a specific interval of time (or space) is known.
- Each outcome is independent.
- The probability that a success will occur is proportional to the size of the interval.
The probability experiment can answer questions concerning the probability of success.
The probability distribution describes the probability of obtaining k successes during a given time interval.
The Poisson distribution was first introduced by French mathematician Simeon Denis Poisson. This distribution was published together with his probability theory in 1837. The work theorised…
