The graph shows three box and whisker plots of blind minus open scores side by side. There is one box and whisker plot for each group: European, ethnic minority group unidentified, and ethnic minority group identitified. The three plots are almost identical. Each shows a central box from about minus 1 to plus 1, with a central line at zero. The whiskers go from minus 4 to plus 4, with 8 points outside the whiskers in total.
