Klemchuk, Bond, and Howell (1990) examined role taking in children. Children were administered a battery of role-taking tasks. They were classified as being in daycare or not being in daycare, and as ages 2–3 or ages 4–5. The hypothesis was that children with daycare experience would perform better on role-taking tasks. The data are available at the book’s Web site as Ex16-19.dat. Run the appropriate analysis.
