pdfF( value, degree of freedom of numerator, degree of
freedom of denominator )
Finds the probability density of a specified value x for the F
distribution that possesses two independent degrees of freedom,
m and n. A list cannot be used.
Limitations: Degree of freedom ≤ 70
• Degree of freedom is a positive real number.
• An error may occur when an extremely large number is entered
for degrees of freedom.
Example
Find the probability density for
the F distribution generated with
degrees of freedom 15 and 10
when x = 3.
cdfF( lower limit, upper limit, degree of freedom of numerator,
degree of freedom of denominator )
Finds the F distribution probability of a specified range x for the F
distribution with two independent degrees of freedom, m and n. A
list cannot be used.
Limitations:
Degree of freedom ≤ 670
• Degree of freedom is a positive real number.
• An error may occur when an extremely large number is entered
for degree of freedom.
Example
Find the probability of the range
x = 0 to 2.5 for the F distribution
generated with degrees of
freedom 15 and 10.
