PART 1

Binary Logistic Regression in SPSS

This week you will build on the simple logistic regression analysis did last week. You will use the same two variables (one independent variable and one dependent variable) you used in your SPSS analysis last week and add a second independent variable to the analysis. How has your statistical significance and odds ratio changed by the introduction of the second independent variable?

To prepare

  • Use the one independent variable and one dependent variable you used to conduct your simple logistic regression analysis in Week 4.
  • Add a second independent variable to your analysis (multiple logistic regression).
  • Remember that your dependent variable must be dichotomous/binary.
  • Think about how you might use the odds ratio in your analysis to simplify the interpretation of your results.
  • How has your statistical significance and odds ratio changed by the introduction of the second independent variable?

The Assignment

Use SPSS to answer the research question you constructed. Then, compose a 1- to 2-paragraph analysis in APA format including discussion of if the predictive relationship is statistically significant and the odds ratio and what it means.

Be sure to include your data output with your analysis. See page 1032 in your Warner textbook for an excellent APA-compliant write-up of a binary logistic regression analysis.

PART 2

Article Critique

The Assignment

Write a 2- to 3-page critique of the research you found in the Walden Library that includes responses to the following prompts:

  • Why did the authors select binary logistic regression in the research?
  • Do you think this test was the most appropriate choice? Why or why not?
  • Did the authors display the results in a figure or table?
  • Does the results table stand alone? In other words, are you able to interpret the study from it? Why or why not?
