    Exclamation Using the average as a basis for evalution in universities

    I need someone to explain why in some universities doctors are judged based on the average of their classes. What I thought is that the average is not fully representative especially when comparing the average of two different sections because you need to find if there is a significant difference or not using the t-test, right? at least the standard deviation should be used along with the average. you can only judge after proving there is a significant difference, what do you think please?

    Comparing averages without any further information leads to useless conclusions at best.

    The t-test is only valid under certain circumstances - if those circumstances are not met then applying the test will lead to invalid conclusions at best.

    A lot of information is required before classes can be meaningfully compared. Much more information than is made available (and perhaps much more information than is even possible to make available ....)

    Who told you that they were? I've never heard of such a thing. (I'm assuming that by "doctor" you are referring to faculty, not medical doctors.)

    Yes I'm talking about "Faculty Members" not medical doctors. I wouldn't ask that question If I haven't had seen people who believe that the average alone is enough to judge a faculty member. I taught for one semester as a part time in one of the universities in my region, and unfortunately not even the measures of variability are taken into consideration; it is only the average that counts and no more no less.
