Hi Again
I recently posted a request for some help with a stats issue. Basically I'm running 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 whereby 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. What I want to know is, Does the stressful task change heart rate?
I asked for some help as to which statistical test I should use to test the relationship. From the very helpful replies I received it seems a repeated measure ANOVA is the most appropriate test (Would everyone agree with this?). What I'm sill unsure about is the variation in heart rate before the stressful task. I'm not expecting personality type to predict heart rate before the stressful task so is variation in pretest heart rate likely to affect the interpretation. Would it be possible to run a repeated disign ANCOVA using pretest heart rate as a covariate in order to control for this variation?
Any help would again be greatly appreciated
Tom
