F-statistic Calculator

Find the F-statistic comparing two variances.

F-statistic 1.563

Formula: F = larger variance / smaller variance

Step-by-step with your numbers:

1. Values used:

2. Variance 1 = 25

3. Variance 2 = 16

5. F-statistic = Variance 1 / Variance 2 = 25 / 16 = 1.563

Did we solve your problem today?

The F-statistic compares two variances, used in ANOVA and tests of equal variance.

The math behind it

F = larger variance / smaller variance. An F near 1 suggests the variances are similar.

Variances 25 and 16 give F = 1.56.

When is F significant?

Compare it to the F critical value for the two degrees of freedom.
