Probability distribution
From the Simple English Wikipedia, the free encyclopedia that anyone can change
A Probability distribution is a term from mathematics. Suppose there are many events with random outcomes. A probability distribution is the theoretical counterpart to the frequency distribution. A frequency distribution simply shows how many times a certain event occurred. A probability distribution says how many times it should have occurred.
There are different probablility distributions. Each of them has its use, its benefits and its drawbacks.
The most common ones are:
- Exponential distribution
- Chi-square distribution
- Normal distribution
- Binomial distribution
- Poisson distribution
