Between-Groups Experimental Design for Studies of Rights and Formula Scoring.
Angoff, William H.
This paper points out that there are certain generalizations about directions for guessing and methods of scoring that require that data be derived from random groups design. It supports the viewpoint that it is neither sufficient nor appropriate to make such generalizations on the basis of an analysis of scores obtained from the answer sheets of only one group of students. An earlier study, using the principle of separate groups for separate instructions, was conducted by administering the SAT-Verbal to four randomly equivalent groups of students. It was found that if two groups were given the test with different directions, those given the test with Rights directions guessed more often and earned significantly higher Rights scores. When their papers were rescored by Formula, the Formula scores came much closer together. The two types of administration-and-scoring were about equally reliable. The correlation between Rights scores on one test and Formula scores on another was about the same as the correlation between Rights and Rights or between Formula and Formula. The approach that an examinee takes in responding to test questions is very much affected by the instructions he or she receives. (LMO)
