Information theory—a new way of leaking at examinations?
J.E. Parrott, D. R. Hub, C. James · Electronics and Power · 1974

For example, it can be shown that an examination question gives little ‘Information’ when there is only a small spread of marks between the candidates or when few candidates attempt the question, thus giving a numerical measure of a previously suspected result.
