In statistics, a contingency table (also known as a cross tabulation or crosstab) is a type of table in a matrix format that displays the multivariate frequency distribution of the variables. They are heavily used in survey research, business intelligence, engineering, and scientific research.
The effect of Yates's correction is to prevent overestimation of statistical significance for small data. This formula is chiefly used when at least one cell of the table has an expected count smaller than 5. = = The following is Yates's corrected version of Pearson's chi-squared statistics:
Fisher's exact test (also Fisher-Irwin test) is a statistical significance test used in the analysis of contingency tables. [1] [2] [3] Although in practice it is employed when sample sizes are small, it is valid for all sample sizes.
Cast the data into an ordered contingency table, with the levels of the independent variable increasing from left to right, and values of the dependent variable increasing from top to bottom. For each entry in the table, count all other entries that lie to the ‘South East’ of the particular entry.
It should only contain pages that are Statistical tests for contingency tables or lists of Statistical tests for contingency tables, as well as subcategories containing those things (themselves set categories). Topics about Statistical tests for contingency tables in general should be placed in relevant topic categories.
TPL Tables has a language for specifying tabulations and controlling format details. This language is the same for both Windows and Unix versions of the software. The Windows version also has an interactive interface that can access most features and includes Ted, an editor used to display PostScript tables on the screen and edit them ...

Under pressure from Fisher, Barnard retracted his test in a published paper, [8] however many researchers prefer Barnard’s exact test over Fisher's exact test for analyzing 2 × 2 contingency tables, [9] since its statistics are more powerful for the vast majority of experimental designs, whereas Fisher’s exact test statistics are conservative, meaning the significance shown by its p ...
