A Chi-Square Test calculator for a 2x2 table. Chi Square Calculator for 2x2. This simple chi-square calculator tests for association between two categorical variables - for example, sex (males and females) and smoking habit (smoker and non-smoker). The Chi-Square Test of Independence is commonly used to test the following: Statistical independence or association between two or more categorical variables. The Chi-Square Test of Independence can only compare categorical variables. It cannot make comparisons between continuous variables or between categorical and continuous variables. Test chí-kvadrát nezávislosti v kontingenční tabulce. Máme k dispozici náhodný výběr rozsahu n rozdělený dle dvou statistických znaků (znak1, znak2), které nám tvoří tabulku, přičemž každý z obou znaků je rozdělen do r (řádky), resp. s (sloupce) skupin. Úkolem testu je rozhodnout, zdali jsou oba znaky na sobě závislé či nezávislé. Fisher's Exact Test Calculator for a 2x3 Contingency Table. 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.

The Chi-Square Test of Independence is commonly used to test the following: Statistical independence or association between two or more categorical variables. The Chi-Square Test of Independence can only compare categorical variables. It cannot make comparisons between continuous variables or between categorical and continuous variables. For one-way frequency tables, the CHISQ option provides a chi-square goodness-of-fit test. The other chi-square tests and statistics described in this section are computed only for two-way tables. All of the two-way test statistics described in this section test the null hypothesis of no association between the row variable and the column variable.
