Explanation:

Discrete Dependent Variables varying from 0 to 20, fit better in a Poisson Distribution. Quantitative Discrete Variables are better designed to distributions like Poisson.

Not all distributions will fit on Normal Distribution (Bell Shaped) that will depend on the dependent variable result. There are many other Distributions, to look for in case our data does not fit on a Bell Shaped one.
