What Statisticians Really Do
We came across these images in a series of humorous montages that professionals had created about what they do. This one was created by Jason Sullivan.
Bad Charts and Good Charts for Kony 2012
We came across this chart from Invisible Children, the group that produced the Kony 2012 video. It shows the organization’s expenditures by category. It is a poorly designed chart for three reasons: 1. The pieces of the doughnut are not correctly proportional. For some reason, the arc widths were compressed for some categories (like Media…
Your Customers DO Care about the Numbers
Coincidentally in the same week that Versta Research published its winter newsletter on Turning Data into Stories: A How-To Guide, last week’s AMA event in Chicago was a market research panel focused on telling stories with data. The presentations were solid, with lots of helpful ideas. But there was also a misguided idea working its…
A Path to Better Research with Geo-Maps
Given how common mapping capabilities have become via the Internet and smartphones, it is surprising that we don’t see more geographic mapping in market research. Researchers nearly always look at customer demographics, and a key component of a person’s demographic profile is where he or she lives. This data is far more compelling if you…
3 Reasons We Don’t Do Statistics in Excel
Over the last few years we have wondered whether spreadsheet software like Excel will soon make statistics software like SPSS or SAS obsolete. Spreadsheets have amazingly powerful and often intuitive capabilities. They have many of the statistical functions we use every day. Younger people entering our profession rarely know programs like SPSS or SAS, and…
A Better Way to Scale MaxDiff Utilities
MaxDiff is a survey method used to measure the importance of product features. Subsets of features are presented, and respondents are asked to select which feature is most important and which feature is least important. Its advantage over other techniques is that by forcing a choice from among multiple features, it more strongly differentiates the…
Three Mistakes to Avoid on Data Charts
Turning data into stories involves not just words, but pictures as well. In the world of quantitative market research, that usually means charts, graphs, and tables. Moreover, just like poorly written sentences that often complicate rather than clarify data, charts and graphs in market research too often suffer from “chartjunk,” as Edward Tufte calls it. …
An Interactive Graph for Choosing Sample Size
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. …
How Data Can Highlight Mistakes
We are often surprised by the number of senior researchers in the market research industry who never touch raw data. Often they don’t even have the tools, since “data processing” is outsourced to lower levels or other countries. It is surprising because we almost always engage in work where getting into the data and puzzling…
Advice for PR Surveys: Avoid Numeric Scales
As much as we love numbers, we find ourselves often advising clients against using numeric scales in their surveys. A numeric scale is any response format that asks people to give a number within a certain range to indicate the strength of their feeling or opinion. The insanely popular survey question used to calculate Net…
