Poisson distribution graph

Answer

Poisson Distribution Graph

The basic shape of a Poisson distribution graph changes. For instance, a Poisson distribution with a low mean is highly skewed with 0 as the mode.

Arguably, all the data will be pushed against 0 and it will have a tail extending to the right side. However, if the mean is larger, the distribution will spread out and become more symmetric.

For instance, consider the example below of Poisson Distribution with mean o.5 and 4. The graphs are as follows.

The illustrations above depicts that the poisson distribution with a larger mean (4) tends to be symmetric.
