How are income and degree related? The American National Election Survey asked respondents who reported at least 13 years of education to identify the highest degree completed (DEGREE: 0 = No degree earned, 1 = Bachelor’s degree, 2 = Master’s degree, 3 = Ph.D., etc., 4 = LLB, JD, 5 = MD, DDS, etc., 6 = JDC, STD, THD, 7 = Associate’s degree. Is there enough statistical evidence to conclude that there are differences in income (INCOME) between people with different completed degrees?
