By Zach Chi-Square Test of Independence Calculator A Chi-Square Test of Independence is used to determine whether or not there is a significant association between two categorical variables. To perform a Chi-Square Test of Independence, simply fill in the cells below for a contingency table of up to 5 rows and 5 columns. Chi Square Calculator for 2x2 This simple chi-square calculator tests for association between two categorical variables - for example, sex (males and females). Chi Squared Goodness of Fit Test Calculator. This online chi squared statistics calculator measures the goodness of fit of the observed frequencies. The measures can be used for testing normality of residuals and Mann Whitney test. 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. Using the Chi Square to p-value calculator. Having obtained a Χ 2 statistic from a given set of data you would often want to convert it to its corresponding p-value. This Chi Square to P-value calculator is easy to use and requires minimum input to get the job done.
