Discussion 2

Part 2

1. Give a plausible example of a three-variable research problem in which partial correlation would be a useful analysis. 

2. Define X1, X2, and Y. Make sure that you indicate which of your three variables is the "controlled for" variable ( X2). 

3. What results might you expect to obtain for this partial correlation, and how would you interpret your results (e.g., spurious correlation, mediation, moderation, and so on)?
