Question

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, an instructor in a large psychology class gave one group of students questions to
be answered while studying for the final exam. The
overall average for 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 σ = 8.4. For
this study, did answering questions while studying
produce significantly higher exam scores? Use a onetailed test with α = .01.
