Enter the larger variance and the smaller variance into the Calculator. The calculator will evaluate the Fmax Test Ratio.

## Fmax Test Ratio Formula

Fmax = LV / SV

Variables:

- Fmax is the Fmax Test Ratio ()
- LV is the larger variance
- SV is the smaller variance

To calculate Fmax Test Ratio, divide the larger variance by the smaller variance.

## How to Calculate Fmax Test Ratio?

The following steps outline how to calculate the Fmax Test Ratio.

- First, determine the larger variance.
- Next, determine the smaller variance.
- Next, gather the formula from above = Fmax = LV / SV.
- Finally, calculate the Fmax Test Ratio.
- 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.

larger variance = 80

smaller variance = 40
