Discussion 1

Now, it’s time to decide which statistical analyses to use to test the hypothesis that your independent variable is related to your dependent variable. For this discussion, provide the following:

The related research question is how stress can have an effect on ones mental and physical well being.

Stress: Dependent

Mental and Physical well being: Independent

• What are your research questions? (Main hypotheses and goal of your study)
• List and specify your dependent and independent variables
• Your choice of statistical test, based on Chapter 7 (Hint: if you have a dependent variable that is ordinal, for this project you can run the statistical test that is appropriate if your dependent variable is continuous.)

Discussion 2

Find a peer-reviewed journal article that interests you and includes the results of one of the statistical tests that we covered this week (one-way ANOVA, odds ratio, or chi-squared test). For this discussion, provide the following:

• A link to the website that contains the article
• What are the research questions? (Main hypotheses and goal of your study)
• List and specify dependent and independent variables cited in the article
• The specific statistical test that was used for hypothesis testing
• The findings, including relevant numbers that help people understand the magnitude of the findings (e.g., two proportions, the mean score for each group, the mean score at each time point)
• Your thoughts about the implications of the findings (what does it all mean?)

Discussion 3

• How do you think two crucial research events—the creation of the Nuremberg Code and the U.S. Public Health Service Syphilis study at Tuskegee—influenced the role of Institutional Review Boards (IRBs) in the study design process?
