WebFeb 14, 2024 · Given that you have a repeated measures design a Chi-square test is not appropriate anymore, since it assumes independence of data. There is no workaround with it, you need a different model. Given that your dependent variable is categorical a logistic regression model could work. WebThe Chi-Square Test of Independence is commonly spent to test the following: Statistical independence or association within two categorical variables. The Chi-Square Test of Independence can only compare categorical variables. It cannot make allegories with continuous variables or between categorical and continuous variables.
