I am a graduate student who is just setting off on her career in analytics and I am delighted there is a community like this one. Now, my first question!
I have a series of variables on which I would like to do a factor analysis and they have to do with respondents' feelings about a decision. Because of the way a question was asked, sometimes saying "true" means 'I feel great!' and sometimes it means 'I feel terrible.'
Do I need to standardize these before doing the factor analysis?
if so, any pitfalls to avoid?
