SPSS question

PUBH 7140-01F-Applied Statistical Methods in Public Health

M6_Assignment

The following rules apply for this assignment:

• If applicable, answer the question under three headings.

1. SPSS syntax

2. Necessary SPSS output

3. Interpretation and/or conclusion of your analysis

• Organize your work in a reasonably neat and coherent way. Work scattered all over the page

without a clear ordering will receive very little credit.

• Only necessary output from the SPSS software should be in the submitted assignment.

• You are required to work INDIVIDUALLY.

• Justification does not include hundreds of pages of computer output with hopes you covered

all aspects. Justification is a well thought out and well-articulated rationale for what you do!

Do not JUST SUBMIT SPSS OUTPUTS or CODES

Researchers want to know if and how the perceived stress can be predicted from participants’ char-

acteristics such as sex, age, and Smoking status. (Hint: Each subject in this survey was given

ten questions related to stress measured by PSS scale. These ten questions were measured on the

same scale of 1 to 5. 1=never and 5=very often. Create a total stress score for each subject by

SUMMING these ten questions (pss1-pss10). For any participant in this study, the maximum score

can be 50, and the lowest can be 5. The total score should be your dependent variable of interest).

Please address following questions by this research question in mind.

1. (5 points) Estimate the regression equation for a research question described above.

2. (8 points) Check the assumptions of multiple linear regression for the research question of

interest. Show your work to justify your conclusion.

3. (10 points) Report your multiple linear regression analysis in APA style.

4. (3 points) Interpret the coefficients βs for all your predictors.

5. (4 points) Report your conclusion about the research question in APA style.
