Research Scenarios- Psych 2219 Research Methods For each of the following scenarios think about and report the following: a. What type of design is being described (correlational, experimental (true IV). quasi-experimental (Selection Variable). is the Independent Variable (IV) or Selection Variable? c. What is the Dependent Variable? d. What statistical test would you run to analyze the results? e. Identify what kinds of control procedures are being used (if described). wno s f. Answer any additional specific questions that are posed for each scenario. that . An educational psychologist was interested in whether using a student's own name in a story affected children's attention span while reading. Age and gender were recorded. Then 20 children were randomly assigned to read a story under ordinary conditions (using names like Dick and Jane). Twenty other children read versions of the same story with each child's own name substituted for one of the children in the story. The researcher kept a careful measure of how sample long (in minutes) it took each child to read the story. expenmental Studly in dupendent t-test TIo-tail test 2. A researcher is concerned that the need for mental health care among prisoners differs according to the type of prison facility. The researcher randomly selects 40 prisoners from each of the three main types of prisons in a particular US state (Low Security, Medium Security, and High Security) and conducts exams to determine their need for mental health care He rates their need for mental health care on a scale from 1 to 20 as well as gender and time spent in prison. 3. A researcher is interested in whether violent TV programs influence behavior of children. Forty young children were monitored closely over a period of several weeks to measure how many hours of violent TV programs they watched and the number of violent actions toward their playmates. Hours spent outside and reading were also re Corelational 4. A schoolteacher has obse rved that students who dress neatly generally did better on tests. To test this idea the teacher had a friend, who did not know the students, rate each of the students for neatness of dress using subcategories which, when combined, ranged on a scale from 1 to 25. A psychologist theorized that people can hear better when they have just eaten a large meal. Six individuals were igned to eat either a large meal or a small meal. After eating, their hearing was tested and they were given a randoml hearing score. In addition, race and weight (in lbs.) were collected. 6. An environmental psychologist is working in a city with high levels of air pollution. This psychologist plans a study of number of problems completed on a creativity test over a 1-hour period. In the experimental condition, each takes the test in a room with a special air purifier. In the control condition, each participant takes the test in a room without the air purifier An organizational psychologist was interested in whether individuals working in different sectors of the differed in their attitudes toward the company measured using a 7 point Likert scale. Volunteers from marketing, and accounting were surveyed. Time with company (in years) was also recorded. company An experiment is conducted in which 60 participants each filled out a personality test of extraversion, but not according to the way the participants see themselves. Instead, 15 subjects are randomly assigned to fill it out according t e way they think their mothers see them; 15 as their father would fill it out for them; 15 as their best friends would fill i out for them; and 15 as their professors would fill it out for them. The personality tests were scored from 1 to 30 with higher numbers indicating greater extraversion. archer is interested in the relation between psychotherapists' degree of empathy and their patients' satisfaction specifying ways to measure variables and the type of statistical test with therapy, Briefly devise a way to assess this by that would provide the most useful information. A doctor is interested in how much taking aspirin is related to the decreased risk of a fatal heart attack. How would you set up this study?

Explanation / Answer

(Since you’ve already mentioned details of the 1st problem, I shall proceed with the 2nd)

2a. Quasi experimental study (because there is no random assignment of participants to different levels of the IV).

2b. The IV: Prison type.

2c. The DV: Mental health care requirement.

2d. A one way ANOVA would be suitable for this study as we want to compare three groups.

2e. The control procedure here is random selection of participants.

Please post the other questions separately as we are supposed to answer just one question or four sub parts of a question.
