Fig. 3. Counts of “best” and “worst” teacher are highly related to teacher relative rank order based on teaching scores. The “best” and “worst” counts and the relative ranks of the faculty are from 5 academic years. Relative ranks are based on teaching scores and were determined for each corresponding academic year. The faculty ranks were binned every 0.1 (10% of the faculty occurred in each bin width). The “best” and “worst” exponential fits have r 2values of 0.97 and 0.96, respectively.
