Hi All,
I have a client who insist on determining which call centre representative
is the weeks best performer. We conduct weekly interviews and ask
respondents to rate each representative. For some reps we conduct 5
interviews others 1 and so on. Now the question is how do you go about
determining which rep performed best, we combine the two top box ratings. We
have looked at margin's of error for each rep but this hasn't proved to be
useful as you will be unlikely to find significant differences with such
small bases sizes. Any suggestion as to the best method to do this would be
appreciated.
Regards,
Grant
