WebThe F-distribution, also known as the Snedecor's F-distribution or the Fisher-Snedecor distribution (after R.A. Fisher and George W. Snedecor), is the distribution of ratios of two independent estimators of the population variances. Suppose we have two samples with n1 and n2 observations, the ratio F = s12 / s22 where s12 and s22 are the sample ...

WebJan 5, 2024 · The F-distribution is a family of distributions. This means that there is an infinite number of different F-distributions. The particular F-distribution that we use for an application depends upon the number of degrees of freedom that our sample has.
