Fisher Exact Test Calculator
Fisher Exact Test: a planned Super Calculator tool. Covers 2 by 2 contingency counts a, b and c. Stub page while the tool and its worked example are prepared.
Fisher Exact Test Calculator is a planned calculator in the mathematics section of Super Calculator, covering statistics and probability.
What this calculator will compute
Inputs: 2 by 2 contingency counts a, b, c, d and tail selection.
Outputs: exact p value, odds ratio, conditional maximum likelihood estimate and confidence interval.
Formula, recorded as scope and not yet verified against a primary source: Exact hypergeometric probability of each 2 by 2 table at least as extreme as the observed one, summed. P(table) = (a+b)!(c+d)!(a+c)!(b+d)! / (n! a! b! c! d!). Two-tailed p sums all tables with probability no greater than the observed table.
