Experimenters provided experts in visual analysis 33 graphical displays of hypothetical data depicted in a multielement experimental design. Participants indicated (a) the presence or absence of experimental control and (b) the degree of experimental control displayed on a 1-100 scale. Each depicted figure systematically varied the number of data paths, the number of data paths elevated above the control, the mean difference between affected test and control conditions, and variability within conditions. These experts’ ratings corresponded across all permutations of data examined, supporting the reliability of visual analysis as an evaluative tool for these designs.
