Prof Gus LaPlace, the Mad Statistician, Was Fiddling Around in His

Prof. Gus LaPlace, the mad statistician, was fiddling around in his statistical laboratory one stormy winter night in 1801. He had a large pile of papers in front of him, each with a measurement written on it. "What would I get,"he mused, "if I counted the number of papers I have, took the square root, and then divided that into the standard deviation of all the measurements? Hmmmmmm. . . Well, maybe I'll do it tomorrow,"he said. If Prof. LaPlace had carried out his plan, he would have discovered (invented?)

A) the standard error of the standard deviation
B) the standard error of the mean
C) the standard error of the median
D) none of the other alternatives are correct.
