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...

Subject bias can occur in an experiment when the participants are aware of the purpose of the study and respond in a way that they think the researchers want. For example, if participants believe they are in a study to test if coffee improves your mood, those who drank coffee might claim to be happier than they really are. Based on the information given, which of the following experiments is most likely to have the issue of a control or...

In this study, participants were randomly assigned to one of two situations – “stress” or “no stress”. They were then put into their assigned fictitious situation and after an hour, were asked to provide an appetite score (Likert-rating). The following data are appetite scores (with higher indicating more of an appetite / i.e. the person is hungry) from 24 participants. Assume data meets all assumptions for a parametric test. Using the information provided, create an SPSS data file and conduct...

What is the independent and dependent variable in this study? Materials and Methods: A randomized controlled study involving patients with major depressive disorder (n = 80) were allocated to two groups, one received standard therapy (antidepressants and counseling) and the other received adjunct yoga therapy along with standard therapy. Ratings of depression and anxiety were done using Montgomery–Asberg Depression Rating Scale and Hospital Anxiety and Depression Scale at baseline, 10th and 30th day. Clinical Global Impression (CGI) Scale was applied...

12 Table 4.4 shows results from the study of diabetic patients discussed in Goldman and Smith (2002). Recall that three groups of patients separated by education level were treated with one of two therapies (conventional vs. intensive). Their average hemoglobin Alc levels (also known as glycosylated hemoglobin) before and after the experiment are reported. Note that, as in golf, lower scores are better on the hemoglobin Alc test, which measures how well the patient has...

High School students were given a short course in basic algebra. Students were randomly assigned to one of the following conditions: courses lasting for 5, 10, or 15 sessions. At the conclusion of the course, participants were asked to take an exam which included several math problems. Before taking the test, participants in each group were offered a monetary incentive-no money, $ 15.00 or $ 30.00 for a certain level of performance. The researcher collected the number of correct answers...

Question 12 0 pts Suppose a hypertension trial is mounted and 18 participants are randomly assigned to one of the comparison treatments so that each treatment group has 6 participants. Each participant takes the assigned medication and their systolic blood pressure (SBP) is recorded after 6 months on the assigned treatment. The ANOVA table is as follows (You should be able to figure out values in the numbered cells): Source Between-Group 2376.8 Within-Group 846.2 Total Sum of Squares df Mean...

1. The pretest-posttest nonequivalent control group design is also very commonly used in psychology. Which of the following is NOT a benefit of using this design when random assignment is not possible: It reduces the threat of assignment bias It limits threats from time-related factors It provides some evidence of a potential cause-effect relationship It rules out differential history effects 2. Particularly when they do not include a control group, pre-post designs are most vulnerable to ____________-related threats to internal...
