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](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F87d67f7c-b9ed-4a61-bd8a-5772302584f1%2F569ad7ef-e9c3-47b7-99b9-786a23470e61%2Featva5k6_processed.jpeg&w=3840&q=75)
