Your homework for this unit is to addressed to scale construction.  You are to go to the General Social Survey site at , go to the "Index by Subject," and select a variable you might be interested in.  Be sure to pick a variable with several indicators measured by the GSS (e.g., Abortion, Affirmative Action).  Select three items that would be appropriate for the creation of a Guttman scale to measure the variable you've chosen.  This means you'll want an "easy" indicator, a "hard" indicator, and one in between, as evidenced by the distribution of responses to each item.  Show the response distributions to justify your choice of items.
