International Organization for Standardization (ISO) and the International Committee on Weights and Measures (CIPM): Switzerland, 1993. U.S. adaptation by the National Institute of Standards and Technology (NIST): Taylor, Barry N. and Chris E. Kuyatt. Measurements & Uncertainty Analysis 2 University of North Carolina The Uncertainty of Measurements Some numerical statements are exact: Mary has 3 brothers, and 2 + 2 = 4. One school of thought is that this means there's something out there in the world that … Estimating Uncertainty in Repeated Measurements Suppose you time the period of oscillation of a pendulum using a digital instrument (that you assume is measuring accurately) and find: T = 0.44 seconds. Example of finding total resistance and associated uncertainty Find the total resistance for two resistors, R 1 and R 2 connected in (a) series, and (b) parallel. This method says that the percent uncertainty in a quantity calculated by multiplication or division is the sum of the percent uncertainties in the items used to make the calculation. 4 Credits. Personal Home Page. The word uncertainty is used a lot in quantum mechanics. E-mail to: Duane Deardorff Office phone: (919) 962-3013 Measurement Uncertainty Quiz Caution: This quiz is not a standardized diagnostic instrument and has not been tested for reliability and validity. Learning how to teach physics using current research-based methods. NIST Technical Note 1297, 1994 ed.. However, all measurements have some degree of uncertainty that may come from a variety of sources. Includes extensive fieldwork in high school and college environments. Teaching and Learning Physics. The uncertainty specified with each measurement is based on the precision of the measuring device and the experimenter’s estimated ability to make a reliable measurement. Research on Measurement Uncertainty Physics 100, Spring 2010 Physics 101, Spring 2008. Meets part of the licensure requirements for North Carolina public school teaching. Recommended Books for physics students Measurements and Uncertainty Analysis Guide for introductory physics students at UNC-CH Measurement Comparison Tool - This Excel file provides a quick and easy way to visually examine measurements and their uncertainties to determine if they agree with each other or are significantly different. The University of North Carolina at Chapel Hill Campus Box 3255 Chapel Hill, NC 27599. Physics104 Summer 2011. 2± 2 2 8 1 0. PHYS 410. This single measurement of the period suggests a precision of ±0.005 s, but this instrument precision may not give a complete sense of the uncertainty. Equipment used: ... email: iliadis@unc.edu Mailing Address UNC Physics & Astronomy 120 E. Cameron Ave. A similar but more complete diagnostic test is being developed, but the subject of measurement uncertainty does not lend itself well to a right/wrong test, so even experts may disagree about which answers are "right" on such a test. The process of evaluating the uncertainty associated with a measurement a) Use the equation a = 2h/t2 to determine the average acceleration and its uncertainty. The process of evaluating the uncertainty associated with a measurement R1 = 50 Ω ± 5%, R 2 = 100 Ω ± 5% Note: Assuming that the 5% tolerance values for each resistor are not correlated, the uncertainty However, all measurements have some degree of uncertainty that may come from a variety of sources.
