A Computer Program for Calculating Standard Deviations from Standard Deviations
Edmund R. Malinowski

December 1995
Vol. 72 No. 12
p. 1077
Abstract
To be scientifically meaningful, a measurement requires that two numbers be recorded: the value of the measurement itself and the uncertainty in the measurement.The uncertainty is usually expressed as a standard deviation which is not always a straightforward computation. It requires special equations for each step in the computations. In this article, we discuss a user-friendly program that not only removes the laborious computational drudgery required by these equations, but also serves as a valuable pedagogical tool. The program we have developed is called Standard Deviations from Standard Deviations (SDSD) and is compiled for use with an IBM PC.
