probability
Probability
firstDegreeOfFreedom
First Degree of Freedom
secondDegreeOfFreedom
Second Degree of Freedom
Returns the inverse of the F probability distribution. If p = FDIST(x,...), then FINV(p,...) = x. The F distribution can be used in an F-test that compares the degree of variability in two data sets. For example, you can analyze income distributions in the United States and Canada to determine whether the two countries have a similar degree of diversity.
