=F.INV.RT(probability,deg_freedom1,deg_freedom2)
=F.INV.RT(0.95,3,4)
The F.INV.RT function can be used to calculate the inverse of the F probability distribution that returns a value of 2.79, which is the inverse of the F probability distribution with a probability of 0.95 and degrees of freedom of 3 and 4, respectively.
=F.INV.RT(0.90,5,6)
The F.INV.RT function can also be used to find the critical value for a given probability and degrees of freedom. For example, if we need to find the critical value for a probability of 0.90 and degrees of freedom of 5 and 6, we can use the function which returns a value of 2.43.
The F.INV.RT function returns the inverse of the F probability distribution and produces an error value if Probability is outside of the permitted range (0 to 1).
