Propagation of errors method
WebFeb 16, 2013 · Propagation of errors is essential to understanding how the uncertainty in a parameter affects computations that use that parameter. The uncertainty propagates by a set of rules into your solution. These rules are not easy to remember, or apply to complicated situations, and are only approximate for equations that are nonlinear in the … WebLecture 3: Fractional Uncertainties (Chapter 2) and Propagation of Errors (Chapter 3) 5 Propagation of Errors with One Variable Arbitrary Function of One Variable Suppose we have a calculated physical quantity q which depends upon a mea-sured physical quantity x according to the general function q = q(x)
