GSS 2014 respondents were asked to rate their level of agreement to the statement, “Scientific research is necessary and should be supported by the federal government” (ADVFRONT). Responses are crosstabulated by educational attainment (DEGREE).
1. What percentage of those with a graduate degree strongly agree or agree with the statement?
2. Interpret the gamma statistic.
3. Test the null hypothesis that DEGREE and ADVFRONT are statistically independent. Set alpha at .05.
