Document Summary

Statistical significance determines whether an observed difference between a treatment group and control group is likely due to chance. Statistical significance in psychological research means that the probability of obtaining an observed effect by chance is small. Although results may be statistically significant, they may not be clinically significant. One way to intensively examine an individual with unique behavioral and physical patterns is to use the case study method. Were the foundation for early psychological developments. Cases studies have been important in history of psychology. Freud"s development of psychoanalytic theory was based on intensive observations from several single cases. Free association emerged out of the case study approach. Unique problems can provide important information about a particular disorder, its causes, and treatment. Correlation is a statistical relationship between two or more variables. Unlike experimental designs, correlational designs do not involve the manipulation of an independent variable.
