Enter the number of individuals in the most abundant species and the number of individuals in the sample into the Calculator. The calculator will evaluate the Berger-Parker Index.

## Berger-Parker Index Formula

BPI = Nm / n

Variables:

- BPI is the Berger-Parker Index ()
- Nm is the number of individuals in the most abundant species
- n is the number of individuals in the sample

To calculate Berger-Parker Index, divide the number of individuals in the most abundant species by the number of individuals in the sample./

## How to Calculate Berger-Parker Index?

The following steps outline how to calculate the Berger-Parker Index.

- First, determine the number of individuals in the most abundant species.
- Next, determine the number of individuals in the sample.
- Next, gather the formula from above = BPI = Nm / n.
- Finally, calculate the Berger-Parker Index.
- 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.

number of individuals in the most abundant species = 37

number of individuals in the sample = 30
