Full Answer

Some psychological problems are more common than most people think; others are exceedingly rare. When working with patients as a counselor, psychologists need to know which conditions are more likely to occur in their patients. While rare problems still occur, examining more common problems first helps psychologist diagnose problems faster. If the diagnosis is unclear, psychologists may rely on statistics to determine which problem is most likely affecting the patient.

Psychological research is a cornerstone of the field, and experimental research helps psychologists provide better treatment for their patients. Statistics are essential for determining if certain treatments are effective. One of the most challenging aspects of psychology is deciding how diseases, disorders and other problems should be categorized. By using advanced statistical analyses, experts can determine which symptoms seem to cluster together.
