- Which of the following is an independent-measures design?
a. All participants perform in every condition
b. Each participant is tested twice, once in each condition
c. Different participants perform in each condition
d. None of the above
Homework Answers
Different participants perform in each condition
Answer to the above question is option C. because An independent measures design consists of using different participants for each condition of the experiment

6. Typically, when comparing a within-subjects design to a between-groups design which of the following describe their differences in error variance? a. Within-subjects designs results in less error variance than between-groups. b. A within-subjects design results in more error variance than a between-groups design. C. A within-subjects design results in the same amount of error variance as a between-groups design d. There is no error variance in a within-subjects design, whereas a between- groups design does present some error variance....

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...

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 a variable of interest and have similar people participate in a different level of the independent variable. have each participant serve in all conditions of the study. use planned comparisons to analyze the results rather than an F test.

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...
