u F Distribution Probability
F distribution probability calculates the probability of F distribution data falling between two
specifi c values.
a : lower boundary
b : upper boundary
Perform the following key operations from the statistical data list.
5 (DIST)
4 (F)
2 (Fcd)
Data is specifi ed using parameter specifi cation. 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)
