F.INV Function

The F.INV function is one of the statistical functions. It is used to return the inverse of the (right-tailed) F probability distribution. The F distribution can be used in an F-test that compares the degree of variability in two data sets.

The F.INV function syntax is:

F.INV(probability, deg-freedom1, deg-freedom2)

where

probability is the probability associated with the F cumulative distribution. A numeric value greater than 0 but less than 1.

deg-freedom1 is the numerator degrees of freedom, a numeric value greater than 1.

deg-freedom2 is denominator degrees of freedom, a numeric value greater than 1.

The values can be entered manually or included into the cells you make reference to.

To apply the F.INV function,

1. select the cell where you wish to display the result,
2. click the Insert function icon situated at the top toolbar,
   or right-click within a selected cell and select the Insert Function option from the menu,
   or click the icon situated at the formula bar,
3. select the Statistical function group from the list,
4. click the F.INV function,
5. enter the required arguments separating them by commas,
6. press the Enter button.

The result will be displayed in the selected cell.
