A forensic psychologist investigated impulsiveness levels in a group of young offenders before and after they completed an intensive cognitive restructuring workshop. Employing a repeated measures design, 17 offenders were assessed before and after the workshop using a standardized impulsiveness questionnaire.
Each participant obtained a unique total score in the before condition, where the maximum possible score was 50 and the median score was 32.
Question: How many of the participants had a score < the median in the before condition? Explain your answer.
