# How do you determine the variance of a Poisson distribution?

The Poisson Distribution is that of a discrete random variable. Hence we use the summation procedure.

The variance of any random variable, X, is defined as

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
