STUDY CONTENT HIGHLIGHTS:
STUDY DESIGN HIGHLIGHTS:
Pre-election interviews 73 minutes in length were conducted September 2 through November 3, 2008. No interviewing was conducted on Election Day, November 4. Post-election interviews 91 minutes in length were administered November 5 through December 30, 2008. Randomization, employed for selection of half-samples to reduce overall interview length, and for question order within batteries, was implemented by the Computer Assisted Interviewing (CAI) instrumentation.
59.5% is what AAPOR calls Response Rate 1 (RR1) for the survey, which is the minimum response rate. It is referred to as the "minimum" because it assumes that in all households at which the eligibility of residents was not determined, at least one eligible adult lived there. AAPOR Response Rate 3 (RR3) assumes that in households at which eligibility was not determined, the proportion of households containing an eligible adult was the same as that proportion among households at which eligibility was determined. That response rate is 63.7%. The maximum response rate, AAPOR's RR5, is 78.2% and is computed by assuming that no eligible adult lived in any of the households in which eligibility was not determined.
For the post-election survey, the minimum rate (AAPOR RR1) is 53.9 percent; the estimated rate (AAPOR RR3) is 57.7 percent; the maximum rate (AAPOR RR5) is 70.8 percent. The re-interview rate is 90.5.
Coded variables for the open-end responses for the ANES 2008 Time Series Study are not present in the study's release data. The codings have been conducted independently by the study's PIs, Jon Krosnick and Arthur Lupia, however all materials from the codings,including data and documentation, are posted by ANES from a link on this page.
