Survey response rates are now staggeringly low—in the single digits. A typical response rate for a relatively high-budget, carefully executed phone survey is merely 9%, down from 36% just fifteen years ago. Here are the numbers from research conducted earlier this year by the Pew Center: If you want to throw money at a survey…
I recently saw a press release about a study showing that only 19.5% of news release headlines are optimized for SEO. It brought to mind all kinds of issues about how best to report numbers in press releases. In particular it highlighted the important issue of whether specific numbers are meaningful and whether they communicate…
Every ten years the Census Bureau provides a count of all people living in the United States. More importantly, the Census Bureau and other agencies conduct ongoing surveys of the population to document crucial facts and figures about who we are. And every year, it seems, these agencies come under attack from politicians who would…
Election years are a perfect time to learn about (and brush up on) the fundamentals of survey research. Not only are the airwaves inundated with public opinion polling, but methodological experts are called upon to talk about developments and current best practices as new technologies and methods become central to measuring consumer and public opinion…
Even if you are not involved in political polling, it is worth paying attention to the methods and best practices of political pollsters. One reason is that few other areas of research offer a way to completely validate one’s methods. Pollsters are using sampling and survey methods to predict the behaviors of a much larger…

It is with good reason that we chuckle when someone tells us that the…
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…
The most recent government estimates of cell phone usage among U.S. households were released a few weeks back, and the pace at which landline usage is disappearing is astonishing. Here are just some of the numbers: Thirty percent of U.S. households do not have a landline telephone An additional 16% have a landline telephone, but…
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…
A good chart is the best way to understand the law of diminishing returns when it comes to sample size. So for our June 2011 newsletter we built an interactive graph for choosing sample size. It’s cool, educational, and useful. Moreover, it will show you just how mind boggling the numbers behind sampling can be. …
