logistic regression
concepts of logistic regression, specifically the odds ratio. In this Application, you will report the odds ratio in a given test.
To prepare for this Application:
• Review Chapter 19 of the Field text for a description of logistic regression and the odds ratio.

• Review the media resources demonstrating the odds ratio.
The assignment:
Complete Smart Alex’s Task #5 on p. 812 of the Field text. Include only Burnout as the dependent variable and Coping Style and Stress from Teaching as the two independent variables. Report the odds ratio ONLY.
Use APA format according to the guidelines in the PASW Application Assignment Guidelines handout. The final document should be 2 pages long.

Logistic Regression
The concept of confounding and how you can use multivariate tests to limit the effect of confounders on the outcomes of tests of the association of dependent and independent variables has been discussed.

Focus on the definitions of confounding and effect modification as presented in the text (Chapter 9):

Also, consider the examples given in the text and the PowerPoint (see Additional Materials) on multiple linear and logistic regression of potential confounders. Then consider the following:

A researcher plans to use a sample of 500 men and women attending a well-known online university to study the relationship between the number of fast-food hamburgers consumed in a month and BMI (body mass index). The null hypothesis is that there is no relationship between fast-food hamburger consumption and BMI.

1. What statistical tests could the researcher use to test the null hypothesis? How might those change if the dependent variable was yes/no obesity instead of BMI?
2. What confounders would you include in your analysis?
3. Explain to your fellow students why it is important to include these potential confounders in any tests of this relationship. Support your opinions with the literature and cite your sources.
