According to Gravetter, Wallnau & Forzano (2018), 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 allowed 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 from the exam was μ = 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 α = .01 to determine whether answering questions while studying produced significantly higher exam scores.
