# WorksheetFunction.F_Dist_RT (Excel)

Returns the right-tailed F probability distribution. You can use this function to determine whether two data sets have different degrees of diversity. For example, you can examine the test scores of men and women entering high school and determine if the variability in the females is different from that found in the males.

If any argument is nonnumeric, F_Dist_RT returns the #VALUE! error value. If x is negative, F_Dist_RT returns the #NUM! error value. If degrees_freedom1 or degrees_freedom2 is not an integer, it is truncated. If degrees_freedom1 < 1 or degrees_freedom1 ≥ 10^10, F_Dist_RT returns the #NUM! error value. If degrees_freedom2 < 1 or degrees_freedom2 ≥ 10^10, F_Dist_RT returns the #NUM! error value. F_Dist_RT is calculated as F_DIST_RT=P( F>x ), where F is a random variable that has an F distribution with degrees_freedom1 and degrees_freedom2 degrees of freedom.

**F_Dist_RT** (Arg1, Arg2, Arg3)

```
Dim dblArg1 As Double: dblArg1 =
Dim dblArg2 As Double: dblArg2 =
Dim dblArg3 As Double: dblArg3 =
Dim dblF_Dist_RT As Double
dblF_Dist_RT = WorksheetFunction.F_Dist_RT(Arg1:=dblArg1, Arg2:=dblArg2, Arg3:=dblArg3)
```

## Arguments

Arg1, Arg2, Arg3Arg1 (Double) - X - the value at which to evaluate the function.

Arg2 (Double) - Degrees_freedom1 - the numerator degrees of freedom.

Arg3 (Double) - Degrees_freedom2 - the denominator degrees of freedom.
