• Resumen

  • 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.1�3In this paper I give three examples in which my students use popular curvefitting software and adjust the theoretical model to account for, and even exploit, the presence of systematic errors in measured data.
