WebMay 15, 2024 · The degrees of freedom for a chi-square test of independence is the number of cells in the table that can vary before you can calculate all the other cells. In a chi-square table, the cells represent the observed frequency for each combination of categorical variables. The constraints are the totals in the margins. Web12. How many variables are present in your cross-classification will determine the degrees of freedom of your χ 2 -test. In your case, your are actually cross-classifying two variables (period and country) in a 2-by-3 table. So the dof are ( 2 − 1) × ( 3 − 1) = 2 (see e.g., Pearson's chi-square test for justification of its computation).
WebMay 24, 2024 · Find the critical chi-square value in a chi-square critical value table or using statistical software. The critical value is calculated from a chi-square distribution. 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.
