Communicating Graphically: Comparing graphical formats and their implications on knowledge and risk perceptions
In one study we randomized participants to receive one of 6 formats that communicated the risks and benefits of treatment: 1) table, 2) pictograph, 3) pie graph, 4) bar graph, 5) modified pie graph (that looked like a clock), and 6) sparkplug. We compared participants' knowledge and risk perceptions across the 6 versions. We found that compared to all graphs, respondents who received the pictographs had better gist and verbatim knowledge. We will also describe how each graph was related to participants risk perceptions.
