Madeleine is an intern at a hospital on a ward that deals primarily with patients who have bi-polar disorder. After a few months, she is slowly becoming convinced that her boss doesn't like her, and is trying to get rid of her by assigning her to work with the most difficult and disturbed patients on the ward. The hospital measures the severity of bipolar disorder in patients using the Structured Clinical Interview for DSM-IV (SCID), which produces a score between 0 and 100 for each patient, 100 being the worst degree of bipolar disorder measurable. She knows that, on average, Bipolar patients score 78.6 on the SCID. She collects the SCID score of the 17 patients she works with, and calculates their average, which is 88.3, and their standard deviation.
