Is it true that the Associated Press refuses to carry stories from online surveys? Yes, as odd as that seems nowadays. But news media face a difficult problem given how easy it is to conduct biased public opinion polling, especially now with online panels and social networks. So some news organizations like the Associated Press…
These days most researchers agree that if you want to do a random sample phone survey of the U.S. population, you ought to include cell phones. More than one-quarter of the population do not have landline telephones at home. Those who do have landline telephones are less likely than ever to answer them, and less…

The idea that online panel surveys can replace telephone surveys ruffles feathers among my colleagues at the American Association of Public Opinion Research (AAPOR). So what would they think of using Twitter posts as a substitute for phone surveys? The idea seems crazy, but as reported in Science, researchers at Carnegie Mellon University have found…
Telephone surveys are still considered the gold standard for rigorous public opinion polling and market research. The reason is that virtually every household in the U.S. can be reached by telephone, and therefore we have careful methods of determining the probability that any individual person is included in a sample to be surveyed. Knowing this…
As an industry driven by data and information, market research and public opinion polling has seen dramatic changes in the last ten years and will no doubt change quickly and in big ways during the next ten. Looking back, here are what we consider to be the five biggest changes that shaped current challenges faced…
