The latest study of Pew Research Center election surveys analyzes the effects of conducting both landline and cell phone interviews. While the addition of cell phones had at most a modest effect on estimates of candidate support in individual surveys, when looked at in the aggregate clear patterns emerge.
Findings from Pew Research Center polls over the year told the story of the longest -- and one of the most exciting -- presidential elections in U.S. history as well as recording the public's reactions to other major events ranging from the pope's visit, to the wars in Iraq and Afghanistan, to the onset of a mega-economic downturn.
In an exclusive interview, Joe Lenski, co-founder and Executive Vice President of Edison Media Research discusses his organization's plans for conducting exit polls on November 4, given this year's special challenges.
Though by no means a perfect instrument, polls make it possible for more opinions, held by a broader and more representative range of citizens, to be known to the government and thus, potentially, heeded.
As in two preceding tests, a new survey shows that including cell phone interviews results in slightly more support for Obama and slightly less for McCain.
The latest Pew Research Center national survey, including a sample of 503 adults on a cell phone, finds that the overall estimate of voter presidential preference is modestly affected by whether or not the cell phone respondents are included.
The Pew Research Center has been studying the challenge to survey research posed by the growing number of wireless-only households. Here's a summary of its latest findings.
Survey research firms face increasingly high non-completion rates. Analysis based on extra efforts to reach non-responders finds few differences between the responses of the easy- and hard-to-reach.
A new Pew study finds that on key political measures such as presidential approval, Iraq policy, presidential primary voter preference and party affiliation, respondents reached on cell phones hold attitudes very similar to those reached on landline telephones.
Several factors deserve exploration, but one should not ignore the possibility of the longstanding pattern of pre-election polls overstating support for black candidates among white voters, particularly white voters who are poor.
