=F.INV(probability,deg_freedom1,deg_freedom2)
=F.INV( 0.9, 2, 5 )
The function evaluates to 3.779716079 if the probability is 0.9 and the numerator and denominator degrees of freedom are 2 and 5.
The F.INV function is used to calculate the inverse of a F probability distribution, which is a measure of variance between two populations. It is an important tool for statistical analysis.
