This calculator will tell you the critical Chi-square (Χ 2) value associated with a given (right-tail) probability level and the degrees of freedom. Please enter the necessary parameter values, and then click 'Calculate'. 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. Chi-Square Calculator. The results are in! And the groups have different numbers. But is that just random chance? Or have you found something significant? The Chi-Square Test gives us a "p" value to help us decide. p-Value Calculator for a Chi-Square Test. This calculator will tell you the one-tailed (right-tail) probability value for a chi-square test (i.e., the area under the chi-square distribution from the chi-square value to positive infinity), given the chi-square value and the degrees of freedom.

### The chi-square statistic for an experiment with k possible outcomes, performed n times, in which Y 1, Y 2,… Y k are the number of experiments which resulted in each possible outcome, with probabilities of each outcome p 1, p 2,… p k is: X² will be larger to the extent that the observed results

Chi square goodness-of-fit calculator online. Chi square Chi-Square Calculator You can use this chi-square calculator as part of a statistical analysis test to determine if there is a significant difference between observed and expected frequencies. To use the calculator, simply input the true and expected values (on separate lines) and click on the "Calculate" button to generate the results. 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. 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.
