I just got chewed out by my boss for modelling the means of some 7-point
semantic differential scales. The scales were part of a written,
self-administered questionnaire, and were laid out like this:
Not stressful 1__ 2__ 3__ 4__ 5__ 6__ 7__ Very stressful
So, why or why not is it kosher to model the means of scales like this?
