Enter the variance of the distribution and into the Standard Deviation of the Poisson Distribution Calculator. The calculator will evaluate the Standard Deviation of the Poisson Distribution.

## 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.

1. First, determine the variance of the distribution.
2. Next, gather the formula from above = STDV = SQRT (V(x) ) .
3. Finally, calculate the Standard Deviation of the Poisson Distribution.
4. 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) )  = ?
