Average Perceived Class Size and Average Perceived Population Density
It is claimed that mean class size, as perceived by students, is always greater than a school's advertised average class size. This article gives a new quick proof, goes beyond previous inquiries to consider the perceptions of students taking multiple classes, and then develops a generalization for average population densities within a state or region. As a bonus, the discussion invokes famous inequalities by Chebyshev and Cauchy.
