Gamma is the appropriate measure of association for two nominal variables with more than two categories. In this case, social class and support are both nominal variables with more than two categories, making gamma the best choice. Spearman's rho is used for ordinal variables, while Phi and Pearson's r are used for nominal variables with two categories.
