Hi everyone,
I had a question regarding blinding outcome assessors.
Can I have different testers for testing people during pre test and post test? Or does it have to be the same people?
I am planning to use the testers who did the pre-test to do the training too. And getting different testers for post-test who are blind to the group allocation or haven't seen the subjects train.
Any thoughts please
Thank you so much,
Anoop
