This study, based on 160 questions of the Pressey Tests includes two numerically equal groups of pupils of eleventh grade American history. Pupils of one group are paired with those of the other group on the basis of the Otis Self-Administering Tests of Mental Ability, Higher Examination. The two groups are designated "the experimental group" and the "control group". Both groups, covering the same material in American history, heard or read each of the 181 terms used in this study. The only known difference being that the experimental group was subjected to one method of drill on the terms, while the control group had no drill. The study attempts to answer the following question: To what extent does one method of drill affect the comparative population estimates of the two groups of test scores?
