Dear All,
Here are two layman questions:
1) I have students' Likert type data of self assessment on writing (set S)
and instructors' Likert type data of assessment on writing of their class
(set I). S contains 25x5 data while I contains 6x5. Would it make sense to
consider students by class and then take average students' self assessment
per class so that I would be able to correlate with instructors' assessment?
2) Age of respondents is categorized (1 if 18 to 25, 2 if 26 to 33, etc.)
Does it make sense or is it possible to calculate mean and variance of
categorized ages?
Hopefully I do not hurt rather I deserve help.
Ray.
