Measuring Systematic Error with Curve Fits
Rupright, Mark E.
Physics Teacher, v49 n1 p54-55 Jan 2011
Systematic errors are often unavoidable in the introductory physics laboratory. As has been demonstrated in many papers in this journal, such errors can present a fundamental problem for data analysis, particularly when comparing the data to a given model. In this paper I give three examples in which my students use popular curve-fitting software and adjust the theoretical model to account for, and even exploit, the presence of systematic errors in measured data.
