The Penny Experiment Revisited: An Illustration of Significant Figures, Accuracy, Precision, and Data AnalysisJoseph Bularzik In this general chemistry laboratory the densities of pennies are measured by weighing them and using two different methods to measure their volumes. The average and standard deviation calculated for the resulting densities demonstrate that one measurement method is more accurate while the other is more precise. Bularzik, Joseph. J. Chem. Educ.2007, 84, 1456.
