Formula and methodology
Formula: F-statistic=numerator variance/denominator variance.
The ratio compares two variance estimates; the chosen numerator and denominator determine the reported F value and degrees of freedom for any later test.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Numerator variance — minimum 1.0E-6; maximum 1000000000000
- Denominator variance — minimum 1.0E-6; maximum 1000000000000
Worked example
| Input | Value |
|---|---|
| Numerator variance | 25 |
| Denominator variance | 16 |
F-statistic = 1.5625.
Assumptions and limits
- Both variance estimates use compatible units and sampling definitions.
- This page calculates the statistic only and does not infer a p-value or critical region.
- Independence, normality, sample sizes, and test design must be checked separately.
