Pleаse write yоur nаme аt the tоp right cоrner of every sheet of paper you use for this portion of your exam. Question #3 - Please label your paper with the correct question number. There is some evidence to suggest that you are likely to improve your test score if you rethink and change answers on a multiple-choice exam (Johnston, 1975). To examine this phenomenon, a teacher gave the same final exam to two sections of a psychology course. The students in one section were told to turn in their exams immediately after finishing, without changing any of their answers. In the other section, students were encouraged to reconsider each question and to change answers whenever they felt it was appropriate. Before the exam, the teacher had matched 25 students in the first section with 25 students in the second section, based on their midterm grades. For example, a student with an 89 on the midterm was matched with a student in the change section who also had an 89 on the midterm. The difference between the two final exam grades for each match pair was computed and the results are shown below. Did the strategy of rethinking and changing answers influence student test scores?
