a questtion about Cronbach's alpha more than 1
Dear All, I am a novice in R and am working on my thesis for master's in Epidemiology & Biostatistics. While calculating Cronbach's alpha for the SF-36 questionnaire, I got all 8 of them more than 1. Is it possible to get alpha more than 1. If yes, please help me understand it. I read about the negative alpha value on your web postings. It does not answer my question though. Thank you.
