Name

FDIST

Synopsis

Use FDIST to find the probabilities associated with the F probability distribution.

To Calculate

=FDIST(X, Degrees_Freedom1, Degrees_Freedom2)

All arguments are required for this function.

X

Specifies a positive numeric value that should be used to evaluate the function.

Degrees_Freedom1

Specifies a numeric value between 1 and 1,000,000,000 that indicates the degrees of freedom for the first data set. This argument is used as the numerator value.

Degrees_Freedom2

Specifies a numeric value between 1 and 1,000,000,000 that indicates the degrees of freedom for the second data set. This argument is used as the denominator value.

Example

Figure 15-13 illustrates how FDIST is used to determine the probability value. You will notice that the value returned by FINV is fairly close to the initial X value of FDIST.

FINV returns a value that matches the initial X value specified for FDIST
