Fix It
Dr. Everdeen is interested in developing a self-report instrument to measure propensity toward violence in teenagers. To that end, she creates a list of 25 items she believes may measure propensity toward violence. Some of the items include "I would never harm my parent/s or sibling/s," "I would never harm my pet/s," and "I would never harm my best friend." Responses to all items are based on a 5-point Likert scale where 1 indicates very true and 5 indicates very untrue. She administers this survey, along with another survey known to identify beliefs supportive of aggression, to five of her closest friends. She finds a strong correlation between the two measures and concludes her survey is a valid and reliable assessment of violent tendencies.
