	I noticed the teacher's curve is symmetrical, and after further inspection it could be interpreted as an edge detection: high values show where an edge occurs. The two highest peaks would nicely align with the edges of the paper, the next highest peaks fit the edges of the table, and the rest could be approximation artefacts, as they're equidistant and rather insignificant compared to those four. I'm not statistics pro, but maybe that rings someone's bells?

	:Interesting observation. It may play into an age-long legend told and re-told among the students that some teachers grade papers by tossing the whole pile in the air; those sheets that land on the teacher's desk get a pass, those falling to the floor get a fail. Sometimes the story gets modified in such a way that papers falling on the teacher's book (or other object) laying on the desk will get a higher marking than those simply hitting the desk. The latter version would explain the higher sheet-size-apart peaks. [[Special:Contributions/108.162.210.111\|108.162.210.111]] 08:57, 26 March 2014 (UTC)		:Interesting observation.

	I teach college courses, and find that exam scores typically do not fit a t distribution, or any symmetrical distrubution. They more often show several groups, or what statisticians call "modes." This is a source of frustration for a lot of teachers. I saw this comic as showing how far from "normal" a real teacher's distribution is. It seems to be two superimposed periodic functions instead of a distribution.
