One critique sometimes heard about NPS scores is that they can’t be stat tested. That is not true. Though I know of no statistical packages that do it automatically, it is an easy calculation you can do on your own. Here’s the math: n = sample size a = % promoters b = % passives…
As more and more people use smartphones and mobile devices to fill out surveys, basic survey design decisions need to be revisited again and again. How should surveys be laid out visually? How should answer scales be constructed? How should people be recruited to take surveys? Some of the latest answers to these questions come…
Back in July we published our newsletter on How to Make Spectacular Infographics, and it became an instant favorite among our colleagues and customers. Then in October, Quirk’s e-newsletter published a version of the article, and in just three months it became one of their most-viewed articles of 2014! It is good to know that…

Ultimately we decided to focus only on the positive “what-to-do” for infographics instead of the negative “what-not-to-do,” so we set those examples aside. Well, along comes the latest news magazine from…
There’s nothing worse than having your research be a pile of numbers with no obvious story. Or maybe there is. What if every random set of numbers told a story? Or, worse yet, what if our brains could find a story in every random set of numbers, even if a story is not there? There…
[SEE CARTOON] Of course those 99% keep reading the pointless polls, and most research firms are happy to keep generating pointless polls. The problem? Too few research firms are willing and able to help clients differentiate a survey that is informative and truly worthy of print, versus one that is pointless. So how do you…
Communicating statistics is sometimes harder than doing statistics. While statistics is all about formulas and logic and precision, words and sentences are all about communicating layers of meaning that are often ambiguous and nuanced. For this reason we often recommend a quick, online refresher course called “Math for Journalists” for our PR, marketing, and journalism…
By which we really mean How to Label Your 11-Point Scale because you shouldn’t be using 10-point scales. Plenty of research shows that numeric scales going from 1 to 10 (ten points) are less effective than numeric scales going from 0 to 10 (eleven points). A recently published article in Survey Practice adds more evidence…
