The Poisson is a discrete random variable. Start by checking to see if the parameters of the data are similar to the Poisson.
Explanation:
The parameters of the Poisson (mean and variance) are equal .
p(x)
where, mean = variance
So, if the discrete data has equal mean and variance, then try using the Poisson.
Hope that helps
