The calculation takes three steps, allowing you to see how the chi-square statistic is calculated. The calculator below should be self-explanatory, but just in case it's not: your chi-square score goes in the chi-square score box, you stick your degrees of freedom in the DF box (df = (N Columns -1)*(N Rows -1) for chi-square test for independence), select your significance level, then press the button. Chi-Square Test for independence: allows you to test whether or not not there is a statistically significant association between two categorical variables. When you reject the null hypothesis of a chi-square test for independence, it means there is a significant association between the two variables.

Chi-Square Di erence Tests 1 Research Situation Using structural equation modeling to investigate a research question, the simplest strategy would involve constructing just a single model corresponding to the hypotheses, test it against empirical data, and use a model t test and other t criteria to judge the underlying hypotheses. 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. A chi-square test for independence compares two variables in a contingency table to see if they are related. In a more general sense, it tests to see whether distributions of categorical variables differ from each another. A very small chi square test statistic means that your observed data fits your expected data extremely well. Typically a chi-square difference test involves calculating the difference between the chi-square statistic for the null and alternative models, the resulting statistic is distributed chi-square with degrees of freedom equal to the difference in the degrees of freedom between the two models.
