Yes, lol, you were! I don’t get to know how others faired that may have chosen opposite dependent variables than I did, because it’s an on-line course, with minimal instructor or peer interaction, unfortunately. Thanks again
I think the lesson in such a class is the professor is only going to make it so complicated. Which is why the suggestion I made actually worked. Its possible as was mentioned you could have dual relationships where both caused each other. But that is not commonly used, it won't work in a regression model. You would need something like structural equation models.
PICOT question: Do more Congestive Heart Failure patients get more Nosocomial Infections than other Cardiac patients on a Cardiac Unit?
Which of those three variables would be Dependent, vs. Independent?
For the record, this is a poorly written question. If it only said "Do CHF patients get more nosocomial infections than other cards patients in the cardiac unit?" this would be more clear. I also only see two variables in the problem, not three; cardiac condition (CHF vs other) and infection status, but maybe I'm missing something?
