How accurate are the results?
We are continuing to explore this question, but over the course of six months from May to October, 2012, we compared results for more than 40 questions asked in dual frame telephone surveys to those obtained using Google Consumer Surveys. Questions across a variety of subject areas were tested, including demographic characteristics, technology use, political attitudes and behavior and civic engagement. Across these various types of questions, the median difference between 48 results obtained from Pew Research surveys and using Google Consumer Surveys was 3 percentage points. The mean difference was 6 points.
