The following are the
two types of Theoretical distributions :

1. Discrete distribution 2. Continous distribution

**Discrete
distribution**

The binomial and Poisson
distributions are the most useful theoretical distributions for discrete
variables.

**Continuous
distribtuion**

The binomial and Poisson
distributions discussed in the previous chapters are the most useful
theoretical distributions for discrete variables. In order to have mathematical
distributions suitable for dealing with quantities whose magnitudes vary
continuously like weight, heights of individual, a continuous distribution is
needed. Normal distribution is one of the most widely used continuous
distribution.

Normal distribution is
the most important and powerful of all the distribution in statistics. It was
first introduced by De Moivre in 1733 in the development of probability.
Laplace (1749-1827) and Gauss (1827-1855) were also associated with the
development of Normal distribution.
