In 1972, half of a group of 111 low-income children from Chapel Hill, NC were randomly chosen for enrollment in an intensive pre-school program, while the other half were not enrolled in any preschool program. 30 years later the preschool group had a higher % attending college, higher average GPA for those who did attend college, and higher average wages than the non-preschool group. Fill in the following table. Is there a control treatment (and, if so, what is it)? Is there any accounting for individual variation? Is there repetition in the experiment? Is the experiment reproducible? Can we say with some confidence that preschool has some lasting effects on career outcomes?
