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....

contrasting a repeated measures research design with matched
subjects and independent measures designs
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...

Be sure to complete each problem in the Hypothesis format and show all work for solution. Assumptions underlying the repeated-measures t test. Individuals with a condition known as "prosopagnosia" cannot recognize faces. Their perceptual abilities are intact, and they can accurately describe feature such as eye color, size of the nose, and shape of the mouth. They can even tell you whether someone is attractive. However, they cannot recognize anyone's face, not even the faces of their friends and family....

Problem Set 2: Two-way mixed design ANOVA (8 pts) Research Scenario: A researcher is attempting to determine the effects of age and sleep deprivation on a reaction time task. Participants (5 “old”; 5 “young”) in an experiment are given a computerized search task. They search a computer screen of various characters and attempt to find a particular character on each trial. When they find the designated character, they press a button to stop a timer. Their reaction time (in ms)...

6. A two-tailed hypothesis test for a repeated-measures research design Previous studies have shown that playing video games can increase visual perception abilities on tasks presented in the gaming zone of the screen (within 5 degrees of the center). A graduate student is interested in whether playing video games increases peripheral visual perception abilities or decreases attention to peripheral regions because of focus on the gaming zone. For his study, he selects a random sample of 81 adults. The subjects...

As a vice-president for Pharmacia (which was acquired by Pfizer in 2003), Dr. Peter Rost was in charge of worldwide marketing for the drug Genotropin, which is a synthetic human growth hormone that is used to treat a limited range of hormonal deficiencies in children and the elderly.42 Beginning in 1997 and continuing to 2003, Pharmacia aggressively promoted Genotropin for conditions beyond those for which the drug had received approval from the Food and Drug Administration (FDA). Physicians may legally...
