PDF-UNCERTAINTIES IN CHEMICAL CALCULATIONS Gary L

Bertrand Professor of Chemistry University of MissouriRolla Background In making quantitative scientific observations there is always a limit to our ability to assign a number to the observation so there is always an uncertainty associated with any. Phys. Accuracy and Precision. The . accuracy. of a measurement tells you how close the measurement is to the “true” or accepted value. . The . precision. of a measurement tells you something about the . Rrs. ) and output ocean color data:. a brief review. Stéphane. . Maritorena. – ERI/UCSB. Uncertainties in output products. Ideally, the uncertainties associated with ocean color products should be determined through comparisons with in situ measurements (matchups). Aims. To be able to calculate the percentage uncertainty of a measurement. To be able to combine these uncertainties to evaluate the overall uncertainty in a derived result. A Speed camera takes two images of a moving car and works out speed by calculating distance/time. How do you think this image would help somebody appeal their fine in court?.

Scientists aim towards designing experiments that can give a “true value” from their measurements, but due to the limited precision in measuring devices, they often quote their results with some form of uncertainty..
