In a study conducted by Zogby International for the Democrat and Chronicle, more than 700 New Yorkers were polled to determine whether the New York state government works. Respondents surveyed were asked questions involving pay cuts for state legislators, restrictions on lobbyists, term limits for legislators, and whether state citizens should be able to put matters directly on the state ballot for a vote. The results regarding several proposed reforms had broad support, crossing all demographic and political lines.
Suppose that a follow-up survey of 100 individuals who live in the western region of New York was conducted. The party affiliation (Democrat. Independent. Republican) of each individual surveyed was recorded, as well as their responses to the following three questions.
- 1. Should legislative pay be cut for every day the state budget is late?
Yes ___ No ____
- 2. Should there be more restrictions on lobbyists?
Yes ___ No ___
- 3. Should there be term limits requiring that legislators serve a fixed number of years?
Yes ___ No ___
The responses were coded using 1 for a Yes response and 2 for a no response. The complete data set is available in the file named NYReform.
