## Standard Deviation of the Poisson Distribution Formula

The following two example problems outline the steps and information needed to calculate the Standard Deviation of the Poisson Distribution.

**STDV = SQRT (V(x) ) **

Variables:

- STDV is the Standard Deviation of the Poisson Distribution ( )
- V(x) is the variance of the distribution

## How to Calculate Standard Deviation of the Poisson Distribution?

The following steps outline how to calculate the Standard Deviation of the Poisson Distribution.

- First, determine the variance of the distribution.
- Next, gather the formula from above = STDV = SQRT (V(x) ) .
- Finally, calculate the Standard Deviation of the Poisson Distribution.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

variance of the distribution = 975

STDV = SQRT (V(x) ) ** **= ?
