A chi-squared test (also chi-square or χ test) is a statistical hypothesis test used in the analysis of contingency tables when the sample sizes are large. In simpler terms, this test is primarily used to examine whether two categorical variables (two dimensions of the contingency table) are independent in influencing the test statistic (values within the table). The test is valid when the test statistic is c… WebMay 24, 2024 · To find the critical chi-square value, you’ll need to know two things: The degrees of freedom (df): For chi-square goodness of fit tests, the df is the number of groups minus one.
