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…
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. …
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.

A truly effective research report is both parsimonious and richly nuanced. In other words, (1) it is short and to the point, and (2) it captures the complexity of reality. But how do you do both?
Data visualization will likely be one the biggest areas of innovation and development over the next several years. This is a good. A chart that clearly and succinctly displays detailed data in a way that captures the viewer’s attention and helps interpret the data can be incredibly powerful. Edward Tufte, a pioneer in this area,…
In the previous post we noted that our industry is driven by data and information, which meant huge changes in the nature of our work over the last ten years. Looking ahead, here are what we predict will be the five biggest trends that will shape market research challenges in the decade to come:
