Part One:

Green & Salkind: Lesson 40, Exercises 1-4

1. Use the method reviewed in the presentation to weigh the cases for this data set. (no points-done in data file)

2. SPSS output; answer a, b, and c beneath output. (2 pts. for output; a-c = 2 pts. each)

3. ---------- 

4. All homework "Results sections" mustfollow the examples given in the SPSS tutorial presentation and the Course Content document "Writing Results of Statistical Tests in Current APA Format" (note: you do not have to refer to a figure).Remember to include a decision about the null hypothesis.

Green &Salkind: Lesson 41, Exercises 1-3

The following helpful tips are numbered to correspond with the exercise number to which they refer (a dash indicates that no tips are needed):

NOTE: This exercise does not use the weighted cases method. Use the data file "as is."

1. Paste SPSS output and answer a, b, d, and e underneath (skip c). For letter "e", this question is asking specifically about effect size. (2 for output; a, b, d, and e = 2 points each)

2. ------------- (3)

3. All homework "Results sections" mustfollow the examples given in the SPSS tutorial presentation and the Course Content document "Writing Results of Statistical Tests in Current APA Format" (note: you do not have to refer to a figure). Remember to include a decision about the null hypothesis.(3)

Part Two:

1. An industrial/organizational psychologist is interested in whether people in different professions prefer different operating systems on their computers. After doing some preliminary research, she chooses three different professions and the three main operating systems available. She interviews 20 people from each profession and asks them to choose their preferred operating system. The results are listed on the following page. Perform a chi square test of independence (using an SPSS two-way contingency table analysis) to determine whether the proportions of operating system preferences differ across the professions. Use the weighted cases method.

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.

TOTAL	17	24	19	60

a) SPSS output 

b) Create a clustered bar graph depicting your results.

c) Write a current APA-style Resultssection based on your analyses. All homework "Results sections" mustfollow the example given in the SPSS tutorials and the Course Content document "Writing Results of Statistical Tests in Current APA Format" (note: you do not have to refer to a figure). Remember to include a decision about the null hypothesis. 

Part Three: Cumulative Homework

1. An admissions counselor wants to find out if TOEFL® scores are predictive of college GPA for international students at a local university. The TOEFL is the Test of English as a Foreign Language, which the school requires for admission, and students can score from 0-120, with 120 being a perfect score. The data from the latest freshmen class are in the table below. Is the TOEFL score predictive of college GPA? Choose the correct test to analyze this question, set up the SPSS file, and run the analysis. Follow the directions under the table below.

TOEFL Score	College GPA
94 80 112 72 93 101 76 90 83 68 113 74	3.4 2.7 3.5 3.1 3.2 3.6 2.8 2.9 3.1 2.4 3.6 2.7

a) Paste appropriate SPSS output. 

b) Paste appropriate SPSS graph. 

c) Write a current APA-style Results section based on your analyses. All homework "Results sections" mustfollow the example given in the SPSS tutorials and the Course Content document "Writing Results of Statistical Tests in Current APA Format" (note: you do not have to refer to a figure). Remember to include a decision about the null hypothesis.
