Chi-Square Test Calculator. This is a easy chi-square calculator for a contingency table that has up to five rows and five columns (for alternative chi-square calculators, see the column to your right). The calculation takes three steps, allowing you to see how the chi-square statistic is calculated. Versatile Chi square test calculator: can be used as a Chi square test of independence calculator or a Chi square goodness-of-fit calculator as well as a test for homogeneity. Supports unlitmited N x M contingency tables: 2 by 2 (2x2), 3 by 3 (3x3), 4 by 4 (4x4), 5 by 5 (5x5) and so on, also 2 by 3 (2x3) etc with categorical variables. Fisher Exact Probability Test: 2x3. A chi-square test will also be performed on the data set, providing that at least 80% of the cells have an expected frequency of 5 or greater, and that no cell has an expected frequency smaller than 1.0.

This calculator compares observed and expected frequencies with the chi-square test. Read an example with explanation . Note that the chi-square test is more commonly used in a very different situation -- to analyze a contingency table. This is appropriate when you wish to compare two or more groups, and the outcome variable is categorical. Choose calculator: 3. Enter data: 4. View results StatMate ® calculates sample size and power. MORE > Analyze categorical data Confidence interval of a proportion or count. Chi-square. Compare observed and expected frequencies. Fisher's and chi-square. Analyze a 2x2 contingency table. McNemar's test to analyze a matched case-control study. There are three ways to compute a P value from a contingency table. Fisher's test is the best choice as it always gives the exact P value, while the chi-square test only calculates an approximate P value. Only choose chi-square if someone requires you to. The Yates' continuity correction is designed to make the chi-square approximation better. The chi-square test of independence is used to test the null hypothesis that the frequency within cells is what would be expected, given these marginal Ns. The chi-square test of goodness of fit is used to test the hypothesis that the total sample N is distributed evenly among all levels of the relevant factor.
