In a study of diagnostic processes, entering clinical graduate students are shown a 20-

minute videotape of children’s behavior and asked to rank order 10 behavioral events on the tape in the order of the importance each has for a behavioral assessment (1 5 most important). The data are then averaged to produce an average rank ordering for the entire class. The same thing was then done using experienced clinicians. The data follow.

Events: 1 2 3 4 5 6 7 8 9 10 Experienced clinicians: 1 3 2 7 5 4 8 6 9 10 New students: 2 4 1 6 5 3 10 8 7 9 Use Spearman’s rS to measure the agreement between experienced and novice clinicians.
