WorksheetFunction.F_Dist_RT Method
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.

Syntax
'Declaration
Function F_Dist_RT ( _
Arg1 As Double, _
Arg2 As Double, _
Arg3 As Double _
) As Double
'Usage
Dim instance As WorksheetFunction
Dim Arg1 As Double
Dim Arg2 As Double
Dim Arg3 As Double
Dim returnValue As Double
returnValue = instance.F_Dist_RT(Arg1, _
Arg2, Arg3)
double F_Dist_RT(
double Arg1,
double Arg2,
double Arg3
)
Parameters
Arg1
Type: System.DoubleX - the value at which to evaluate the function.
Arg2
Type: System.DoubleDegrees_freedom1 - the numerator degrees of freedom.
Arg3
Type: System.DoubleDegrees_freedom2 - the denominator degrees of freedom.
Return Value
Type: System.Double
Remarks
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.
