Hermann Rorschach, a Swiss psychiatrist, began to get an inkling of an idea in 1911. By 1921 he had developed, tested, and published his test, which measures motivation and personality. One of the several ways that the test is scored is to count the number of responses the test-taker gives (R scores).
The data in the table are representative of those given by people with schizophrenia, depression, and those with no diagnosable disorder.
Analyze the data with an F test and a set of Tukey HSDs. Determine d for the schizophrenia-depression comparison. Write a conclusion about Dr. Rorschach's test.
