A group of researchers are studying depression in a sample of patients. Each researcher independently assesses the level of depression in each patient, but their assessments do not match. The problem with the research is that:
A) depression cannot be studied scientifically.
B) the researchers do not have an objective measure of depression.
C) there are too many researchers.
D) the patients are not really depressed.
Answer: B
Rationale: Objective measurements are measurements that, within an allowed margin of error, are consistent across instruments and observers. In this example, the fact that different researchers cannot agree on the depression levels in the same patient indicates that they are not using an objective measurement.
