WebStep 1. calculate expected counts under the independence model. Step 2. compare the expected counts E i j to the observed counts O i j. Step 3. calculate X 2 and/or G 2 for testing the hypothesis of independence, and compare the values to the appropriate chi-squared distribution with correct df ( I − 1) ( J − 1)
