Exact r×c Contingency Table: How many rows? columns?

You are about to enter your data for an exact contingency table analysis. For this to make sense you should have a table of data (at least 2x2; maximum: 6x6).

Exact analysis of large contingency tables is uncommon: it is mostly used to solve the problem of sparsely populated tables. If your table's cells are all larger than 4, X2 is probably what you want!

For exact analysis of 2x2 tables you may prefer the following (faster) "one-sided" analysis.

Number of rows:
Number of columns:

You must have data for each box in the table: no blanks allowed!
