单选题Students: Pass or Fail When students who are taking a course for regular grades are compared with students who are taking the same course on a pass-fail basis, the graded students achieved higher grades. The comparison is made possible by not telling the instructor which students are taking the course on the pass-fail basis and having him or her assign letter grades to all students. The registrar converts these to pass-fail for those students who had previously elected this option. This provision is included to protect the pass-fail students from possible instructor bias. The data clearly show that there is a difference in grades between the two groups of students in the same class, those electing to take the course for pass-fail and those taking the course for regular letter grades. The interpretations of this difference, however, vary widely. Some claim that this difference proves that pass-fail students simply don"t work as hard or take the course seriously as students taking the course for letter grades. Other claim that this difference proves that only the less competent students elect the pass-fail option. Others claim that this difference proves that students only take their most difficult (for them) courses under the pass-fail option and therefore are exploring areas they might otherwise attempt to avoid. Others claim that this difference proves that students use the pass-fail option only in courses where the teacher is so personally uninspiring as to need the threat of letter grades in order to goad the students into studying. What, in fact, do the data really prove? Nothing, other than that a difference in grades does indeed exit between the two groups. All the previously mentioned explanations are only hypotheses, that is, guesses about the possible reason for the difference. One or even several of these hypotheses might eventually be proved valid, but at present none of the studies really proves any of the hypotheses. Yet, in the hands of a statistical charlatan, the data may seem to an unsophisticated audience to prove whatever he or she says they prove. The most common error in reading and interpreting research studies is assuming that a casual factor has been isolated when, in fact, it has not. As will be seen, most studies in the field of educational psychology do not allow for a cause-and-effect interpretation, and yet it is extremely tempting them as though they did. This is probably the major booby trap awaiting the unwary student. Just because two variables are associated doesn"t necessarily mean that one is the cause of the other.
