Note. Mean, SD, and minimum–maximum values are based on the 100-point scale assessing whether the graph displays experimental control. Proportion is the proportion of the raters who indicated the graph did display experimental control using the yes–no measure. (Rows in boldface correspond to the graphs in Figure 1.)
