A graduate student is interested in whether journaling can affect grief and healing. She has participants who have been widowed within the past 10-14 months complete a battery of psychological questionnaires before and after journaling about their daily problems for 2 months. The first time the graduate student conducted this study, she used a repeated-measures design and compared the widows' and widowers' baseline scores with their scores...

7. An advantage of the matched groups research design is that it: provides a less ambiguous interpretation of the results than the repeated measures design. has more statistical power than the between-groups design with random assignment. requires fewer research subjects than the repeated measures design. has more statistical power than the repeated measures design. 8. One way to increase the statistical power within a between-groups design is to: have each participant contribute two data points per condition. match participants on...
