Comparison of distributions
Previous Up


The three common distributions are all different but, at certain limits, they become similar to each other.




  • For example, for a given m, as we make n large (and p small), the binomial distribution becomes like the Poisson distribution.
  • If the mean, m increases to a large value, both the binomial and Poisson distributions become more symmetrical and can be approximated by a Gaussian distribution.
  • To set s for the Gaussian, type a value in the rectangle and hit 'submit'.

Vary parameters to find when the binomial distribution approaches the Poisson distribution or when all 3 distributions are similar.
