The main difference between the test for goodness of fit and

The main difference between the test for goodness of fit and the test for independence is that:

a. the goodness of fit test can be used only for 2 × 2 designs whereas the independence test is not limited to a particular design type.

b. expected frequencies are calculated for the independence test but not for the goodness of fit test.

c. the goodness of fit test is limited to one nominal variable whereas the independence test is not.

d. observed frequencies are compared to expected frequencies for the independence test but not for the goodness of fit test.

Solution

a. the goodness of fit test can be used only for 2 × 2 designs whereas the independence test is not limited to a particular design type.
