# 10 Best Free Online F-Distribution Calculator Websites

Check out these **best free online F-Distribution calculator websites**. F-distribution is referred to as Snedecor’s F-distribution. It is also known as Fisher-Snedecor distribution. It is the distribution of ratios of two independent estimators of the population variances. To calculate F-distribution or f-value, you need the Probability level along with the Numerator Degree of freedom and Denominator Degree of freedom.

This post covers 10 free websites with F-Distribution calculators. These calculators are available to use right away. You can simply visit the direct link added alongside the calculator in the post. This opens the respective calculator where you can add your data and get the f-value. Some of these calculators can also calculate the p-value (probability level) from the f-value. Then some can also plot cumulative distribution functions and generate a distribution table as well. You can go through the post and check them out in detail.
