Jalopy June is unhappy with the results of her previous survey analysis and decides to revamp her Empathy Survey. She reworks the survey and administers it to a group of social work clinicians and a group of teen bullies. The social workers score significantly higher than the bullies, with the score indicating a high level of empathy. Jalopy June is pleased because she can now prove that her instrument has: Reliability, Known-groups validity, Discriminant validity, Predictive validity.
