Research the Carolina Abecedarian Project at Read the content on http://abc.fpg.unc.edu. the Home page to learn about the study design. Part A: The project was an Select an answer study. Part B: How were the children organized into groups? By socioeconomic class: lower, middle, and upper-class groups By random assignment By gender: males in one group, females in another group By race/ethnicity Part C: Now select and review "Follow-Up Studies." If the randomization process created the groups to be similar enough, we can infer that the treatment is the cause. Under this assumption, make an inference about the treatment's effect relating to college-going behaviors. O There is evidence that attending college contributes to a higher likelihood of being in the intervention group. There is evidence that the intervention contributes to a higher likelihood of attending college.

Question
Part D: The sample used in the Carolina Abecedarian Project is not representative of the entire population of American infants. Still, there may be a sampling frame--a subset of the population that the sample does represent. Because the participants in the study were born in the mid-1970s and were from low-income families, the sampling frame or subset represented by the study was low-income children in the mid-1970s. (Although not mentioned on this website, they were also mostly African American.) Experiments focus on making inferences about treatments, but treatments are applied to populations. Would it be reasonable to infer that all children who attend quality preschool would receive benefits similar to those observed in the study? Yes O No
