Data is specified using parameter specification. The following shows the meaning
of each item.
Lower ............. lower boundary
Upper ............. upper boundary
n - df ................. numerator degrees of freedom (positive integer)
d - df ................. denominator degrees of freedom (positive integer)
Execute .......... executes a calculation
Example To calculate F distribution probability for a specific parameter
value
For this example, we will calculate F distribution probability
when lower boundary = 0, upper boundary = 1.9824, n - df = 19
and d - df = 16.
