“…About 1.6% of printed graphs are 3-dimensional (Zacks, Levy, Tversky and Schiano 2001) though the use of such graphs at scientific meetings may be much larger, because some people like them (Stewart, et al 2009) and software such as Microsoft Excel and PowerPoint makes them easy to create. Pie charts are more frequently used in the popular press than in scientific publications, but even in the popular press, bar charts outnumber pie charts (Spence 2005).…”

Graphs and tables are an effective means of communication. However, relatively little experimental work exists examining differences between various formats in how well people understand provided information. We conducted two web-based experiments with a large, diverse sample to explore the effects of display format on respondents' comprehension. We found that comprehension depended on task. Graphs were better for estimating differences; however, tables were better when estimating equality and sums. We found 3D display formats reduced comprehension of pie charts but not of bar charts. Although pie charts never assisted comprehension, they often did not significantly impair comprehension either. Comprehension based on a 3-way table was as good as that for clustered bar charts but was worse for divided bar charts. Information can be conveyed graphically even with 3-way tables, but the choice of display format needs to be sensitive to the task at hand.

“…For example, although pie charts are used very frequently to communicate various statistical facts, the scientific evidence about their usefulness is equivocal. 10,12,13 The first aim of this article is to develop a scale that can be used to assess the graphical literacy skills needed to understand risks in the health domain. To date, graph understanding has not been assessed by any health literacy instrument.…”
