Using GSS 2014 data, we take another look at BUYPOL, buying products for political, ethical, and environmental reasons. Earlier in this chapter, we examined the relationship with political party identification and BUYPOL, finding no significant relationship between the variables. Here we identify social class (CLASS) as the independent variable and BUYPOL as the dependent. SPSS Anova results are presented.

1. Set alpha at .05. What do you conclude about the relationship between social class and BUYPOL?
2. What is the eta-squared for this model?
3. If alpha were set at .01, would your decision change? Explain.
