(9 points) This question asks you to make sense of regression results based on the information provided. Each observation is an individual. The dependent variable is a measure of whether the individual participates in groups (social, political, etc.). Higher values indicate more participation. Each column in the table below lists coefficient estimates from a separate regression, and each row corresponds to one of the independent variables in the regression. Standard errors are in parentheses. The independent variables are characteristics of the area where the individual lives. "Size of place" is the population, "Med HH income" is median household income, Gini is a measure of income inequality (higher values mean more inequality), Race and Ethnic are alternative measures of ethnic diversity. Describe what we learn from this table and briefly discuss by referring to the issues we talked about in class.
