Re: st: 1-4 scale

[Nick Cox <njcoxstata@gmail.com>]

I recommend the spelling Likert, given that the term refers to a  
person, Rensis Likert. Some people would use each such variable as if  
it were a quantitative predictor; others would use a set of factor  
variables. On the information you give it sounds more like the second.
