SPSS Homework 1 Instructions: One-Sample t Tests and Paired-Samples t Tests (40 points)
When submitting this file, be sure the filename includes your full name, course and section. Example: HW1_JohnDoe_355B03
Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05 unless otherwise noted in the problem. Also, remember that we divide the p value in half when reporting on one-tailed tests.
Part One:
Problem Set 1: The single-sample t test
File: Open “Module 1 Exercise File 1” found in Blackboard Course Content (Course Guides and Assignment Instructions—Assignment Instructions—SPSS Homework—SPSS Homework 1 Files).
Research Scenario: A clinical psychologist conducts group therapy with military veterans and wants to determine whether their scores on the Revised UCLA Loneliness Scale (R-UCLA-LS; Russell et al., 1980) are different from those in the general population. She administers the R-UCLA-LS to a group of 12 veterans and enters their scores into an SPSS data file (Exercise File 1). She knows that the population mean on the R-UCLA Loneliness Scale is 37, with higher scores indicating higher levels of loneliness. Conduct a single-sample t test to determine whether combat veterans score differently than the general population on the R-UCLA-LS.
Respond to the following items:
1. Paste SPSS output (2 pts). Beneath the output, type the answers to the following questions:
a. Mean R-UCLA-LS score for the sample of veterans (2 pts)
b. Standard deviation of the scores for the sample of veterans (2 pts)
c. p value (significance) of the test (2 pts)
2. Create a histogram that demonstrates the distribution of scores. Be sure to correctly label the X and Y axes and give your graph a title. (2 pts)
3. Write an APA-style Results section based on your analysis. All homework Results sections should follow the example given in the SPSS tutorials. Remember to include a decision about the null hypothesis. (3 pts)
Problem Set 2: The paired-samples t test
File: Open “Module 1 Exercise File 2” found in Blackboard Course Content (Course Guides and Assignment Instructions—Assignment Instructions—SPSS Homework—SPSS Homework 1 Files).
Research Scenario: A researcher is interested in whether pairs of identical twins have different SAT scores in late high school. She collects scores from a sample of 10 pairs of twins and enters them into an SPSS data file, labeling the groups as “Twin 1” and “Twin 2” (Exercise File 2). Conduct a paired-samples t test to determine whether there is a difference in SAT scores between twins.
Respond to the following items:
1. Paste SPSS output (2 pts). Beneath the output, type the answers to the following questions (2 pts. each):
a. Based on the research scenario, is the likely null hypothesis for this study that twins will score a) the same or b) differently on the SAT? Choose one, and use the information you have learned about hypothesis testing (from reading, presentations, PSYC 354 etc.) to support your answer.
b. Based on the SPSS output, what is the mean SAT score of the “Twin 1” group?
c. Based on the SPSS output, what is the standard deviation of the “Twin 2” group?
2. Create a boxplot that illustrates the differences between the groups of twins. (2 pts)
3. Write an APA-style Results section based on your analysis. All homework “Results sections” should follow the example given in the SPSS tutorials. Remember to include a decision about the null hypothesis. (3 pts)
Part Two:
Problem Set 1: The single-sample t test
Research Scenario: A college professor administers a vocational interest inventory to a sample of math majors at the university where he teaches. He believes that they will have higher scores on the “Analytical” scale than students in the general population, who normally score a 38. The table below shows the scores of the math majors on the “Analytical” scale of the vocational interest inventory. Using the table, enter the data into a new SPSS file and conduct a one-sample t test to evaluate whether these scores are significantly higher than those of the general population of college students.
The steps of the test will be the same as the ones you have been practicing in Part One of the assignment—the only difference is that you are now responsible for creating the data file as well. Remember to name and define your variables under the “Variable View,” then return to the “Data View” to enter and analyze the data.

essay Analysis
Analysis
| Emory and Jim Morris strolled back to their plant from the administrative offices of Ferguson & Son Manufacturing Company. Tom is manager of the machine shop in the company’s factory; Jim is manager of the equipment maintenance department. The men had just attended the monthly performance evaluation meeting for plant department heads. These meetings had been held on the third Tuesday of each month since Robert Ferguson, Jr., the president’s son, had become plant manager a year earlier. As they were walking, Tom Emory spoke: “Boy, I hate those meetings! I never know whether my department’s accounting reports will show good or bad performance. I’m beginning to expect the worst. If the accountants say I saved the company a dollar, I’m called ‘Sir,’ but if I spend even a little too much—boy, do I get in trouble. I don’t know if I can hold on until I retire.” Tom had just been given the worst evaluation he had ever received in his long career with Ferguson & Son. He was the most respected of the experienced machinists in the company. He had been with the company for many years and was promoted to supervisor of the machine shop when the company expanded and moved to its present location. The president (Robert Ferguson, Sr.) had often stated that the company’s success was due to the high-quality work of machinists like Tom. As supervisor, Tom stressed the importance of craftsmanship and told his workers that he wanted no sloppy work coming from his department. When Robert Ferguson, Jr., became the plant manager, he directed that monthly performance comparisons be made between actual and budgeted costs for each department. The departmental budgets were intended to encourage the supervisors to reduce inefficiencies and to seek cost reduction opportunities. The company controller was instructed to have his staff “tighten” the budget slightly whenever a department attained its budget in a given month; this was done to reinforce the plant manager’s desire to reduce costs. The young plant manager often stressed the importance of continued progress toward attaining the budget; he also made it known that he kept a file of these performance reports for future reference when he succeeded his father. Tom Emory’s conversation with Jim Morris continued as follows: Emory: I really don’t understand. We’ve worked so hard to meet the budget, and the minute we do so they tighten it on us. We can’t work any faster and still maintain quality. I think my men are ready to quit trying. Besides, those reports don’t tell the whole story. We always seem to be interrupting the big jobs for all those small rush orders. All that setup and machine adjustment time is killing us. And quite frankly, Jim, you were no help. When our hydraulic press broke down last month, your people were nowhere to be found. We had to take it apart ourselves and got stuck with all that idle time. Morris: I’m sorry about that, Tom, but you know my department has had trouble making budget, too. We were running well behind at the time of that problem, and if we had spent a day on that old machine, we would never have made it up. Instead, we made the scheduled inspections of the forklift trucks because we knew we could do those in less than the budgeted time. Emory: Well, Jim, at least you have some options. I’m locked into what the scheduling department assigns to me and you know they’re being harassed by sales for those special orders. Incidentally, why didn’t your report show all the supplies you guys wasted last month when you were working in Bill’s department? Morris: We’re not out of the woods on that deal yet. We charged the maximum we could to other work and haven’t even reported some of it yet. Emory: Well, I’m glad you have a way of getting out of the pressure. The accountants seem to know everything that’s happening in my department, sometimes even before I do. I thought all that budget and accounting stuff was supposed to help, but it just gets me into trouble. It’s all a big pain. I’m trying to put out quality work; they’re trying to save pennies. |
