Students explore about propagation of error in calculations using experimental data. They develop their weighing and pipetting techniques. Students explore the following terms: Standard deviation and relative standard deviatin. They investigate about the larger the glassware, the lower the relative standard deviation and the lower the proagated error. Full Review »
