Statistics help psychologists know to what extent certain psychological problems are common. They are also needed for psychological research. Statistics are prevalent in psychological literature, and all psychologists need to know how to interpret the analyses they read.
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.
Clinical psychologists need to keep up with an ever-changing base of literature, and these papers are filled with statistical information. By learning how to correctly interpret this data, psychologists can ensure that their treatments are in line with contemporary psychological research.
