Solution to question on a study of applications to medical school, 6

The graph shown does make any connection between the paired scores on the blinded and open forms. One possibility would be to plot the differences between masked and open, like this:

Three box and whisker plots of blind minus open scores side by side, for European, ethnic minority unidentified, and ethnic minority identitified. d

Several other approaches could be used, but there are too many points for scatter diagrams.

Back to question.
