This is a Fisher exact test calculator for a 2 x 2 contingency table. The Fisher exact test tends to be employed instead of Pearson's chi-square test when sample sizes are small.
2024年9月4日 · This Fisher's exact test calculator computes both the one-tailed and two-tailed p-value for a Fisher's exact test on any 2 x 2 contingency table. To compute the p-value of other statistical tests, visit our p-value calculator .
Fisher's Exact Test is used to determine whether or not there is a significant association between two categorical variables. It is typically used as an alternative to the Chi-Squared Test (2x2 table) when cell counts are small.
费舍尔精确检验计算器. Fisher 精确检验 用于确定两个 calcategories 变量之间是否存在显着关联。. 当 2 × 2 表中的一个或多个单元格计数小于 5 时，它通常用作独立性卡方检验的替代方法。. 要执行费舍尔精确检验，只需填写下面的列联单元格，然后单击“计算 ...
Fisher's exact test is used to calculate P values for small sample sizes. It was created for a specific (and rare) experimental design where marginal totals are fixed. It's called an exact test, but that can be misleading because it's only exact if your experiment
2020年4月27日 · This calculator performs Fisher's Exact test on a contingency table based on user provided input.
Fisher's exact test computes the probability, given the observed marginal frequencies, of obtaining exactly the frequencies observed and any configuration more extreme.
This calculator uses the Freeman-Halton extension of Fisher's exact test to compute the (two-tailed) probability of obtaining a distribution of values in a 2x3 contingency table, given the number of observations in each cell.
This calculator will compute both the exact hypergeometric probability and the exact two-tailed probability of obtaining a distribution of values in a 2x2 contingency table using Fisher's exact test, given the number of observations in each cell.
Compute the exact two-tailed and hypergeometric probabilities of obtaining a particular distribution of values in a 2x2 contingency table using Fisher's exact test, given the number of items or observations in each cell.
