Unit 10- Written Assignment Unit 7
Instructions
Load the data file called unit 10_SPSSHW7_data_regression.sav. This is a data file based on a 1991 U.S. General Social Survey. First, familiarize yourself with the variables; the data file contains more than 40 variables for each of about 1500 respondents. The variable “prestg80” is a scale (i.e., continuous) variable that codes a respondent’s occupational prestige (a higher value indicates a more prestigious occupation). You will investigate which other variables predict the occupational prestige score by conducting the following:
1. Conduct a multiple regression to determine whether and to what extent occupational prestige is predicted by the following variables: respondent’s sex, general happiness (happy), number of children they have (childs), the highest year of school completed (educ), and whether the respondent takes illegal drugs (hth5) or has a drinking problem (hlth4). Make sure to check diagnostics and remedy any problems before moving on to #2 below. Think about the different assumptions of a regression. Do the results indicate you have met the assumptions? (4 points)
2. Report the results of the analysis (Hint: please refer to the textbook for information about the appropriate way of presenting results). Make sure to report the following (include tables):
a. method of entry of variables (4 points)
b. significance of all effects (2 points)
c. standardized beta coefficients of all effects. (2 points)
d. standardized confidence intervals of all effects (4 points)
3. Interpret the results, focusing on the relative strength and reliability of effects. (3 points)
4. Save and submit the SPSS syntax and output files used to complete items 1-2 above. The file names should begin with your first and last name followed by the homework number (e.g., John Doe HW7.sps; John Doe HW7.spv). (1 point)
