I have a huge dataset of faculty evaluations of students – at different grade levels
6 evaluative items;
I want to calculate z-scores--- within grade levels
But wonder – should I calculate individual z-scores for each of the 6 items?
Calculate an average of the 6 items and then calculate a z-score for that?
Any insights would be greatly appreciated.....thanks!
