Statistical distributions

Know your data first. Discrete, use: Poisson, for discrete events that are independant of each other. E.g. car accidents at a junction.

Binomial Distribution Normal distribution,. also known as the Gaussian distribution, is a continuous probability distribution that is widely used in statistics, science, engineering, and other fields.

E.g. height of adult people weights etc. The normal distribution arises naturally from many real-world processes.
