Answer to Question #91104 in Mechanics | Relativity for Schazee Cansino

Question

Give an example of data and solution for estimating errors from multiple measurements of a physical quantity using variance.

Answer 1

This is an example where one quantity is the product of two quantities divided by a third. The relative measurement errors of the last three - A, B and C - are known, then the relative error of the calculated value R is the arithmetic sum of the relative measurement errors of the three mentioned.
