Enter the first variance and the second variance into the Calculator. The calculator will evaluate the F Critical Value.

## F Critical Value Formula

F = s1^2 / s2^2

Variables:

• F is the F Critical Value ()
• S1 is the first variance
• S2 is the second variance

To calculate F Critical Value, square the first variance then divide by the square of the second variance.

## How to Calculate F Critical Value?

The following steps outline how to calculate the F Critical Value.

1. First, determine the first variance.
2. Next, determine the second variance.
3. Next, gather the formula from above = F = s1^2 / s2^2.
4. Finally, calculate the F Critical Value.
5. 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.

first variance = 1

second variance = 0.9
