Linear Multiple Regression

Linear Multiple Regression
This week, you have expanded on your knowledge of multiple regression to work with linear multiple regression. In this Application, you will perform a linear multiple regression analysis.
To prepare for this Application:
• Review Chapter 8 of the Field text for a description of the linear multiple regression and an example of conducting a linear multiple regression using PASW.
• Review Chapter 5 from the APA manual, “Displaying Results.”
• Review the media resources demonstrating the linear multiple regression.

The assignment:
Complete Smart Alex’s Task #5 on p. 355 to complete the linear multiple regression analysis using the Child Aggression.sav dataset from the Field text.However, use only the variables Aggression (DV), and test to see if Sibling Aggression is a mediator of the relationship between Parenting Style and Aggression or whether Sibling Aggression is a moderator of the relationship.
You can follow the steps outlined on pp. 331–354 as a guide. Report your findings in APA format according to the guidelines in the PASW Application Assignment Guidelines handout. The final document should be 2 pages long.

• Website: Cengage Research Methods Workshops
http://www.wadsworth.com/psychology_d/templates/student_resources/workshops/resch_wrk.html

This website offers many useful workshop topics such as experimental methods, reliability and validity, surveys, sampling methods, ethical issues, and evaluating published research.
Statistics and SPSS
• Website: SPSS Solutions for Education: Student Resources
http://www-01.ibm.com/software/analytics/spss/academic/students/resources.html

The SPSS student support site provides a knowledgebase and allows students to request assistance from SPSS Technical Support staff. Since this site is produced and maintained by the creators of the PASW software, it is the best place to go when you have a question about the software.
• Website: UCLA’s ‘What Statistical Analysis Should I Use?’ Table
http://www.ats.ucla.edu/stat/mult_pkg/whatstat/default.htm

This statistics table shows general guidelines for choosing a statistical analysis, and links showing how to do such tests using SAS, Stata and PASW. This is a good place to go if you are not sure which statistical test would best answer the research question you have.
