Do Americans have a higher Socioeconomic Status (SES) and education level when belonging to a union? I created 3 dummy variables for the independent variable, “Does R (respondent) or spouse belong to a union” using the High School Longitudinal Study dataset. My reference variable assumes that neither the respondent or spouse belong to a union. Further, the model summary indicates 34% of SES values are affected by the independent variables and the ANOVA test reveals a significance level of .000, well below the conventional threshold of .05, indicating unions do influence SES and education levels (Laureate, 2016). In examining the coefficients, SPSS reveals when comparing SES against married couples who are not in the union, SES increases 2.5 – 2.8 units when one spouse belongs to the union, 2.2 units when both spouses belong to the union. Therefore, when comparing respondents, spouses, or married couples within a union, SES increases and so does their higher education level by 4.245 years. Diagnostics reveals a Durban Watson value of 1.75 and ANOVA value of .008. Further, the collinearity VIF values for each dummy variable are well below 10 at just above 1.0. Lastly, Cooks Distance values are well below 1.0 and do not have undue influence (Laureate, 2.16m). References
