Project R-3 Allocation of Students Among Groups.
Sumner, G. C.
This report describes an objective method for allocating San Jose students to groups so that each group would include the same representation of students according to two quantitative measures of scholastic achievement. The conditions provided that each group be internally heterogeneous, but that intergroup differences be small, so that each would represent a separate replication of the same experiment. The allocation was to mirror uniformly the central tendency and variability of the overall student population. This method could apply to a more flexible set of initial conditions: it could accommodate another variable, be equally useful for ensuring representation across socioeconomic or cultural variables, and obtain proportionality with the racial-ethnic mix of the student population considered.
