NOTE: This exercise does not use the weighted cases method. Use the data file “as is.”
1. Do a, b, c, d, and e. For letter “e”. This question is asking specifically about effect size. (3 for output; a-e = 2, 2, 3, 3, 3)
2. ------------- (3)
3. All homework “Results sections” should follow the example given in the Course Content document “Writing Results of Statistical Tests in APA Format” (note: you do not have to refer to a figure). (3)
Part Two:
1. An industrial/organizational psychologist is helping a company determine the type of work stations preferred by its employees. The business owner believes that people who work in different departments may prefer different work station layouts. In order to examine this claim, the I/O psychologist sets up three simulated work stations: private office (PO), semi-private office (SPO), and open floor plan (OFP). She recruits employees from 3 different departments: Information Technology, Human Resources, and Marketing. The participants spend 30 minutes in each simulated work station performing general pre-arranged tasks. At the end of the 1.5 hours, the participants turn in a form on which they mark which work station they prefer. The results are listed below. Perform a chi square test of independence (using an SPSS two-way contingency table analysis) to determine whether the proportions of work station preferences differ across departments. Use the weighted cases method explained in the text.

The steps 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 the data. (3)
Private Office | Semi-Private Office | Open Floor Plan | TOTAL | |
Information Technology | 9 | 6 | 4 | 19 |
Human Resources | 6 | 10 | 3 | 19 |
Marketing | 7 | 3 | 9 | 19 |
TOTAL | 22 | 19 | 16 | 57 |
2. Create a clustered bar graph depicting your results. (3)
3. Write an APA-style results section describing the outcome. All homework “Results sections” should follow the example given in the Course Content document “Writing Results of Statistical Tests in APA Format” (note: you do not have to refer to a figure). (3)
Part Three: Cumulative Homework
1. A researcher wants to find out if the number of absences from a chemistry class are predictive of final exam scores at a local university. The data from the past term are in the table below. Are number of absences predictive of final exam scores? Choose the correct test to analyze this question, set up the SPSS file, and run the analysis. Follow the directions under the table below.
Number of absences | Final Exam Scores |
1 1 2 3 4 5 5 5 6 6 6 7 7 | 98 95 89 89 80 85 80 75 76 69 70 62 60 |
a) Paste appropriate SPSS output. (3)
b) Paste appropriate SPSS graph. (3)
c) Write an APA-style results section describing the outcome. All homework “Results sections” should follow the example given in the Course Content document “Writing Results of Statistical Tests in APA Format” (note: you do not have to refer to a figure). (3)

1. Green & Salkind: Lesson 42, Exercises 1, 3, and 4 MODULE 8 Do both of them and don't forget the dropbox.(Remember you should have a part a and b part)
The following helpful tips are numbered to correspond with the exercise number to which they refer (a dash indicates that no tips are needed):
1. This research scenario will be familiar to you. Do letters a, b, and c, answering the questions beneath your SPSS output.
3. All homework “Results sections” should follow the example given in the Course Content document “Writing Results of Statistical Tests in APA Format” (note: you do not have to refer to a figure).
4. Create a boxplot as done in earlier modules.
2. Green and Salkind Lesson 43 Exercises 1 and 2:
1. This scenario will also be familiar to you. Answer the last question concerning follow-up tests beneath your SPSS output.
2. Effect size must be computed by hand (or calculator) using the formula given in the lesson for eta squared.
Part Two:
1. A university assessment department collects data to determine whether class ranking differs between male and female students. Based on the top 12 males and top 12 females of the senior class, is there a difference between genders on where they are ranked in their class? Perform a Mann-Whitney U test, being sure to follow the directions below the table.
Male | Female | |||
2 5 7 10 11 13 15 16 18 21 23 24 | | 1 3 4 6 8 9 12 14 17 19 20 22 | | |

*NOTE: Your file should be set up in the same manner as the example data file and the exercise file from part 1, with a grouping variable and a dependent/test variable. Because these are class rankings, they are ordinal data and should be identified as such in “Variable View” under the column “Measure.” Click in the cell under “Measure” in the row for your class rank variable, and choose “Ordinal.” This ensures that SPSS treats the data at the proper level of measurement.
2. Create a boxplot depicting the results.
3. Write an APA-style results section describing the outcome. All homework “Results sections” should follow the example given in the Course Content document “Writing Results of Statistical Tests in APA Format” (note: you do not have to refer to a figure).
Part Three: Cumulative Homework
1. An organizational psychologist wants to find out if job satisfaction ratings differ as a function of department (human resources, sales, and research and development) and/or time of shift (early, late). Choose the correct test to analyze this question, set up the SPSS file, and run the analysis. Follow the directions under the table below.
| Early shift | Human Resources | Sales | Research and Development |
10 16 12 16 9 | 19 21 16 18 | 17 21 18 14 | |
| Late shift | 14 13 8 12 12 | 17 12 14 9 10 | 12 15 19 14 |
a) Paste appropriate SPSS output.
b) Paste appropriate SPSS graph.
c) Write an APA-style results section describing the outcome. All homework “Results sections” should follow the example given in the Course Content document “Writing Results of Statistical Tests in APA Format” (note: you do not have to refer to a figure).
