This program finds the exact probability of a 2x2 table

by Fisher's exact test; limited to 70 subjects

For the TI-82:





This program allows to calculate the exact probability

of a 2x2 table by Fisher's exact test.

You must first enter the number of 'successes' and

'failures' in the 'experimental' and 'control' groups.

The total number of subjects must be < 70 because

70! Overflows the TI-82.

This program can certainly be improved.
