The F-Test Calculator helps you determine if two population variances are equal. Calculate the F-statistic and degrees of freedom (df1, df2) quickly for hypothesis testing and ANOVA. Input your sample variances and sizes to get instant results, essential for statistical analysis and research.
Formula:
The F-statistic is calculated as the ratio of two sample variances:
F = s₁2 / s₂2
Where:
- s₁2 = Variance of Sample 1
- s₂2 = Variance of Sample 2
The degrees of freedom for the F-distribution are:
- df₁ = n₁ - 1 (Degrees of freedom for Sample 1)
- df₂ = n₂ - 1 (Degrees of freedom for Sample 2)
Where:
- n₁ = Size of Sample 1
- n₂ = Size of Sample 2
