Hello all.
I'm very new to stats and I'm hoping some of you kind people may be able to help me out. I'm runnuing an experiment to look at the relationship between personality and physiological reaction to a stressful event. I have three personality variables, Toxic achieving; Non-toxic achieving; and Anxious-tense. These are continuous variables, each participant has a score on each of the personality variables. I then have two heart rate variables, one measured before and one after a stressul task. I therefore have five different variables. What I want to do is to compare heart rate before and after a stressful task and to see whether the personality variables have any influence on this.
I'm unsure of a couple of things. Firstly i'm not sure what are my IV's and what are my DV's. I think personality type would be an IV. However, I'm not sure if it's one IV with 3 levels or whether it's three seperate IV's. I think heart rate is my dependent variable but again I'm not sure what type of DV it is. That is, I'm not sure whether is's a single DV measured pre- and post-test or whether it's two seperate DV's.
Secondly I'm not sure what statistic test I would you to look at the realationship I mentioned above. This partly because I'm unsure of the IV/DV's. Any suggestions as to what test I should use?
Any help would be greatly appreciated.
Tom
