Polling assessing opinion

Polling: Assessing Opinion

  • How do we know?: Ask everyone or sample the population

  • Why sample:

    • Efficient way to get information

    • Sample size determines margin of error (smaller samples have higher errors)


Polling samples

Polling: Samples

  • Recent Gallup Poll

    • Results are based on telephone interviews with 1,014 national adults, aged 18 and older, conducted April 5-8, 2004. For results based on the total sample of national adults, one can say with 95% confidence that the margin of sampling error is ±3 percentage points.

Polling explaining things

Polling: Explaining things

  • Exit polling common in politics to help explain outcomes:

    • For example: NH exit polls after primary

      • Kerry carried voters who wanted a viable candidate

      • Kerry ahead w/voters who cared about health care and economy

      • Dean ahead with wanting a candidate close to their own position

      • Dean carried anti-Iraq war voters.

      • Edwards ahead with those who cared about the ‘tone’ of race


Polling tracking responses over time

“In general, how would you say things are going for the U.S. in Iraq?”

Polling disaggregating the data

Polling: Disaggregating the Data

  • Demographic or other background variables often key:

    • Gender

      • Gender gap in politics: Men favor Bush over Kerry (46 to 38%) Women favor Kerry over Bush (50 to 37%)*

    • Age

    • Race

    • What else would be important?

  • Other background variable depending on the study

    • DCE report:

      • CS vs non-CS students

      • Students who had prior distance learning experiences vs. not
