Describe the relationship between how a person does on a test, compared to a national mean and standard deviation, and how a person might feel about their score. For example, if one had a history of major depression and scored a 15 on the test just discussed, how might their interpretation of their score differ from an individual who has never dealt with depression and receives a score of 15?
