On: How much are professors paid?

> aggregated statistics (across all fields, all ranks, tenure-track/non-tenure-track, etc) are useless because of the variance

Could you expound on that? How does the variance in underlying data cause aggregated statistics to lose usefulness?

[jknz → klank]

Say you receive an offer for a specific position in a specific department and hope to negotiate a better salary. Aggregated data averaged across all fields, all universities and all ranks is not useful. However, the salaries of recent hires, for the same specific position, in the same field at comparable universities will give objective data (and possibly leverage) to negotiate your offer.
