F Test Variance Calculator

Compare sample variances with F statistic and degrees of freedom.

F Test Variance Calculator compares variances of two samples to test whether spread differs significantly. It is useful when checking homogeneity assumptions before other statistical tests. The tool computes F statistic and significance from sample variance inputs. Use it as part of variance analysis workflows.

F-test Samples

Enter numeric lists for both samples.

Result

Variance A: 2.00000000

Variance B: 2.00000000

F statistic (>=1): 1.00000000

DF1/DF2: 5 / 5

How to use this tool

Enter sample sizes and variances for both groups.
Run the F-test to compute test statistic and p-value.
Use results to assess whether variance difference is statistically meaningful.

Hypothesis testing resources

Recommend biostatistics books, stats calculators, and lab analysis platforms.
