Today we did stats and what stat test to use : I then gave them a resource I found but couldn't answer the first question as the class was divided as to what level of measurement was being used.
so - please confirm this for me
A psychologist was interested in looking at the relationship between time taken to get to work and stress levels.
Participants were asked to 1. record time it took. 2. grade themselves on a scale how stressed they felt after the journey
Is this ordinal, interval or ratio data - I'm confusing myself greatly here ! ( once we work this out we can decide what test to use )
Thank you for any help !
