For a given probability, the Excel FINV function computes the inverse of the (right-tailed) F Probability Density function.
Syntax :
=FINV( probability, deg_freedom1, deg_freedom2 )
Parameters :
probability –
deg_freedom1 –
deg_freedom2 –
Example :
The right-hand chart depicts the reverse of the right-tailed F. Distributions with one degree of freedom in the numerator and two three rotational in the decrease. If you wish to determine the value of this function for a chance of 0.2, you may use the Finv function, as follows:
This gives the result 3.555555556.
