Weinstein, McDermott, and Roediger (2010) report that students who were given questions to be answered while studying new material had better scores when tested on the material compared to students who were simply given an opportunity to reread the material. In a similar study, a group of students from a large psychology class were given questions to be answered while studying for the final exam. The overall average for the exam was m = 73.4 but the n = 16 students who answered questions had a mean of M =78.3 with a standard deviation of s = 8.4. Use a two-tailed test with a = .01 to determine whether answering ques- tions while studying produced significantly higher exam scores.
