Web Survey Bibliography  Title How To Ensure the Accuracy Of
Internet Research Year 2001 Access date 20.04.2004 Abstract
Harris Interactive predicted the US election outcome with 99%
accuracy. These internet-only results outperformed every survey
conducted by telephone and the state by state forecasts were
almost twice as accurate as comparable phone forecasts. George
attributes part of the success of Harris’ internet polling to
the use of propensity score adjustment, a statistical substitute
for probability sampling. In this session he will discuss how
sampling issues can be overcome and why the internet may be more
representative and accurate than traditional methodologies.
