WebThe test first tabulates the data in a K Ktable and then performs Bowker’s (1948) test for table symmetry and the Stuart–Maxwell (Stuart1955;Maxwell1970) test for marginal homogeneity. Both the symmetry test and the marginal homogeneity test are highly significant, thus indicating a shift in public opinion.
