PH 307 Fall 2021
Assignment #5 – Using SPSS to Analyze Health Data
Due: Wednesday, December 8, 2021, 4:00 PM
It is preferred that students work in pairs on the assignment, with one assignment submitted per pair; both students in a pair will receive the same grade. It is strongly recommended that both students actively participate in preparing the assignment. If, instead, partners choose to split the assignment (with each being responsible for different parts of the assignment), be aware than one person’s poor/non-completion of his/her portion is NOT an acceptable reason for submitting the assignment late. You may work with a student in the Wednesday section; if you do, please note that when you upload your assignment. (Although Assignment 1 is due at a later date for the Wednesday section, your assignment is due on your due date.)
To complete this assignment, you will need the following files:
a) Your SPSS data file (.sav file) used in Assignment 4
b) OSHPD Documentation
c) CA County Codes
The OSHPD Documentation and CA County Codes can be found on the Assignment 5 page.
INSTRUCTIONS – READ CAREFULLY
These instructions apply to all parts of Assignment 5. Points are associated with all instructions; not following the instructions will result in a loss of points and can have a significant impact on your grade.
Copy the results from your SPSS output file into a Word document. (Add your answers and output to this document.) All answers should be in complete sentences. Statistical tests must include complete interpretations along with the SPSS output.
Name the Word document as follows: OurLastNamesFirst Initials_Assign5.docx (or MyLastNameFirst Initial_Assign5.docx), where you replace OurLastNamesFirst Initials (or MyLastNameFirst Initial) with your first initials and last names (e.g., WolfJ_LoboJ_Assign5.docx). Your name(s) must be a part of the file name. Please also type your name(s) at the top of the Word document. Your SPSS data file (.sav file) should be named in the same way as the Word document. Upload both the Word document and your SPSS data file (.sav file) to Canvas on the Assignment 5 page.
You must include the log that describes the recoding of all variables needing to be recoded and all syntax used to answer the questions. Your SPSS data file (.sav) should match your answers. (In other words, I should be able to run the analyses from your SPSS file and get the same results you report.) You are required to type the values into the variable view of the SPSS file for all variables that you use, including the original variables you recode; your interpretations must use the category names and not simply the codes used in SPSS.
Read each question carefully.
