摘要:The communication of uncertain and certain information is essential for individual behaviour and decision making. But many subjects have difficulty in understanding uncertainty-related problems. This difficulty can depend on the way in which materials are presented and communicated: for example, whether this is verbalnumerical or graphical. We measured subjects’ performances when solving uncertainty- related problems in relation to the format of problem presentation, aiming to detect the graphical facilitation effect potentially produced by Euler-Venn and Iconic diagrams. Through a quasi-experimental mixed design, we analysed the performance of 229 undergraduate students in solving two paired uncertainty-related problems under conditions of time pressure. Applying a non-parametric statistical data analysis, we found a graphical facilitation effect, particularly with Euler-Venn diagrams.
