The "Closed School-Cluster" Method of Selecting a Probability Sample.
Shaycoft, Marion F.
In some educational research studies--particularly longitudinal studies requiring a probability sample of schools and spanning a wide range of grades--it is desirable to so select the sample that schools at different levels (e.g., elementary and secondary) "correspond." This has often proved unachievable, using standard methods of selecting school samples. The "closed school-cluster" method, a way of selecting a probability sample with the desired characteristics, has now been developed. Its description and the instructions for implementing it are presented, along with the necessary formulas, including one for determining differential weights for the students in the sample. (Author)
