I am a psychology student using SPSS to analyse my data.
I have 2 conditions of the IV of treatment (treatment or no treatment) to test pain tolerance levels which is measured by the DV of pulse rate to measure pain.
The study used a repeated measrures design using a counterbalancing approach (e.g. 20 particpants in treatment condition first, wheras other 20 in no treatment condition first, and then in alternate condition in second part of experiment.
I've used paired samples t-tests to test for difference between both conditions, but now i want to test for order effects, to see if particpants who took part in whichever condition first, got higher scores.
Is there any ANOVa's i would use for this and how would i interpret it using what tests?
