Hi. I have a couple of questions about the controversial Likert scales.

1) what are the "acceptable" statistical analysis procedures for the responses of one sample. No comparison of groups.

2) can the same scale have both agreement and frequency items? Or the anchor must be fixed eg. totally disagree to totally agree.

3) When exploratory factor analysis is applied, what is the best extraction and the best rotation methods you suggest?

Thanks in advance for your contributions...
