For each of these ANES-based scenarios, describe which advanced technique a researcher might want to use and why:

a. a researcher wants to analyze the interaction between income and political views with regard to his or her dependent variable:

people’s attitudes toward limiting corporations’ contributions to campaigns (hint: look at this particular variable).

b. a researcher wants to explain Americans’ attitudes toward Affirmative Action (hint: look at the distribution of the Affirmative Action Index).

c. a researcher wants to explain support for environmental legislation, using the Environmental Index as his dependent variable. For his or her independent variables, the researcher wants to use some personal characteristics of the respondent (such as gender and political views) and some legislative data from the respondent’s state of residence (such as the stringency of environmental laws in the state).
