Here’s a useful way to think about statistical significance. When looking at your data, what’s the probability that it looks like something is there, when in fact nothing is there. Randomness in data (because of sampling) often causes illusions. So testing for significance is all about measuring whether the patterns we see in our data…
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…
Every day I get a digest of new posts from R-Bloggers, a community of 555+ bloggers who are devoted to using R and sharing what they learn with others. Even though you can’t learn how to use R by reading these posts, once you’ve jumped into the world of R with an in-depth tutorial or…
When we published our July 2014 newsletter on How to Make Spectacular Infographics, we spent some time looking for examples of poorly done infographics.

When customers talk about wanting faster and cheaper research, we’ve learned they’re not clamoring for all research to be faster and cheaper than ever before. Rather, they’re looking for new methods and niche solutions that fit specific problems they face. The distinction is crucial, because the first pushes us to automate, routinize, outsource, and make…
Versta Research’s winter newsletter comes out next week, which will focus on some new approaches to faster (and cheaper) market research. In the meantime we have been thinking a good deal about where to invest in new methods and innovation during the coming year so that we continue to make our work better and smarter…
We have been experimenting with the idea and the process of using infographics for all our research studies at Versta. Infographics are not easy, because they require careful attention to the data, to the succinct story that the data tells, and to graphic design. But so far I have been struck by how compelling research…
