 How do I calculate Cronbach’s alpha for a construct used over several subjects?
I've asked for the opinion's about several different subjects, all with the same items/constructs. So now I have to calculate Cronbach's alpha for the construct to see if it is valid, using not just the answer from one subject but the answers of all 20 subjects together. How do I do that?

Are you asking how to use SPSS for this? Try a quick UCLA review at What does Cronbach’s alpha mean? You might use that example to explain where you are in your work. — Tom
