This project involves the use of the SPSS data file Health Control.  Read the description of the data file on page 353 in the appendix of the text.  Then do each of the following:

 

(1) Use the Analyze> Descriptive Statistics> Frequencies options in SPSS to see the range of values entered for each variable and to assess the number of missing values in the data.  In a word-processed document, begin a report titled “MATH 214 Project” (with your name at the top), and write a first paragraph which indicates whether each variable in the data file should be treated as qualitative or quantitative, and for each variable include explanation of why.  In a second paragraph, discuss how the range of values for each variable compares with what is stated in the description of the data file in the appendix of the text.

 

(2) Use SPSS to decide whether each of the three “locus of control” scores can be considered as having come from a normal distribution.  Write a third paragraph in the document titled “MATH 214 Project” discussing the results indicated on the SPSS output.

 

(3) A researcher has decided to perform three hypothesis tests to see if there is any evidence at the 0.05 level of a difference in mean between the “internal health locus of control” score and the “powerful others health locus of control” score, between the “internal health locus of control” score and the “chance health locus of control” score, and between the “powerful others health locus of control” score and the “chance health locus of control” score.  Use SPSS to perform appropriate hypothesis tests, and in a fourth paragraph, state why you chose the hypothesis tests you used, and discuss the results of these hypothesis tests with correct usage of grammar and statistical notation.

 

(4) A researcher has decided to perform three hypothesis tests to see if there is any evidence at the 0.05 level that of a difference between males and females for each of the “internal health locus of control” score, the “powerful others health locus of control” score, and the “chance health locus of control” score.  Use SPSS to perform appropriate hypothesis tests, and in a fourth paragraph, state why you chose the hypothesis tests you used, and discuss the results of these hypothesis tests with correct usage of grammar and statistical notation.

 

The final version of the project you submit should consist of (1) a hard copy of the appropriate title page, (2) a hard copy of the word‑processed document consisting of the five paragraphs described above,  and (3) a hard copy of all the relevant SPSS output.  The word‑processed document will be graded for correct summaries of statistical results and for correct usage of grammar and statistical notation.

The due date for the first draft of the project is Monday April 7.  This first draft will be returned to you, after which you have the option of submitting a second draft to earn back points lost on the first draft.  The due date for the second draft of the project is Monday April 14.
