# F.INV

### Description

Returns the inverse of the F probability distribution. If p = F.DIST(x,...), then F.INV(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 income diversity.

### Sample Usage

### Syntax

F.INV(probability,deg_freedom1,deg_freedom2)

The F.INV function syntax has the following arguments:

Probability Required. A probability associated with the F cumulative distribution.

Deg_freedom1 Required. The numerator degrees of freedom.

Deg_freedom2 Required. The denominator degrees of freedom.

### Remarks

If any argument is nonnumeric, F.INV returns the #VALUE! error value.

If probability < 0 or probability > 1, F.INV returns the #NUM! error value.

If deg_freedom1 or deg_freedom2 is not an integer, it is truncated.

If deg_freedom1 < 1, or deg_freedom2 < 1, F.INV returns the #NUM! error value.
