List mates:
I have a study where I randomly assigned participants to completing one of two versions of the same scale so that I could determine whether a change in wording made any difference in scores. I computed separate Cronbach's alphas for each version of the scale.
My question is, how would I test whether the two alphas are significantly different?
Thanks for your help. Lise
