Public Opinion Fall 2009 Instructor: Kent Tedin Answer four questions (The questions to be answered will be selected by the instructor on the day of the exam) 1. When it comes to public opinion surveys, what is sampling error and what is the confidence level? If a sample of 600 shows 30% approve of the way Barak Obama is doing his job as President, how is that number interpreted in terms of sampling error and the confidence level? Discuss how random digit dialing works and how sampling is done within households. 2. What are straw polls? Why was the Literary Digest so off the mark in its 1936 Presidential election survey? Why was the Gallup Poll wrong in 1948 when it predicted that Dewey would beat Truman? Why was Connie Chung wrong in 1992 when, following the State of Union address, she told Dan Rather and a TV audience that “53% were financially worse off than five years ago. It is important to note that this is quite dramatic.” 3. Answer the following regarding question wording effects.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
