A psychologist has constructed a paper & pencil test
purported to measure depression. To see how the test
compares with the ratings of experts, 12 "emotionally
disturbed" individuals are given the paper & pencil test.
The individuals are also independently rank-ordered by
two psychiatrists according to the degree of
depression each psychiatrist finds as a result of
detailed interviews. The scores are given here. Higher
scores represent greater depression.
