Fischer t test
Fisher's exact test is a statistical significance test used in the analysis of contingency tables. Although in practice it is employed when sample sizes are small, it is valid for all sample sizes. It is named after its inventor, Ronald Fisher, and is one of a class of exact tests, so called because the significance of the deviation from a null hypothesis (e.g., P-value) can be calculated exactly, rather than relying on an approximation that becomes exact in the limit as the sample size grows to infi… WebDec 16, 2016 · fisher.test (contingency) which outputs this: Fisher's Exact Test for Count Data data: contingency p-value < 2.2e-16 alternative hypothesis: true odds ratio is not equal to 1 95 percent confidence interval: 6.103516e-05 4.703333e-03 sample estimates: odds ratio 0.000701445.
