SCIENCE MEASUREMENT AND UNCERTAINTY ACCURACY AND PRECISION DEMYSTIFYING SCIENTIFIC DATA RET 2006 REV 2 ANSWERS
Scientificuncertaintyis a quantitative measurementof variability in the data. In other words, uncertaintyin sciencerefers to the idea that all data have a range of expected values as opposed to a precise point value. This uncertaintycan be categorized in two ways: accuracyandprecision.

Was this helpful?People also askWhat is measurement and uncertainty?What is measurement and uncertainty?In metrology,measurement uncertainty is the expression of the statistical dispersion of the values attributed to a measured quantity. All measurements are subject to uncertainty and a measurement result is complete only when it is accompanied by a statement of the associated uncertainty,such as the standard deviation.Measurement uncertainty - WikipediaSee all results for this questionWhat is percent error and uncertainty?What is percent error and uncertainty?Percentage uncertainty is also a measure of accuracy,but in a different way than from percentage error. It's a measure of your accuracy while doing the experiment. Percentage error is a measure of the accuracy of your final result. Overall,percentage uncertainty improves the accuracy of the experiment because you now have a wider range of results.Accuracy and percentage uncertainty - Physics ForumsSee all results for this questionWhat is uncertainty in physics?What is uncertainty in physics?uncertainty principle. n. (General Physics) the principle that energy and time or position and momentum of a quantum mechanical system,cannot both be accurately measured simultaneously. The product of their uncertainties is always greater than or of the order of h,where h is the Planckconstant.Uncertainty principle - definition of uncertaintySee all results for this questionWhat is uncertainty in chemistry?What is uncertainty in chemistry?Uncertainty in measurement results is the probable amount error or doubt associated with an individual measurement,or a set of measurements,as a result of both systematic and random variances. Uncertainty is not equivalent to error,but the two are related.Why Is Measurement Uncertainty Important? - EzineArticlesSee all results for this questionFeedback

B. Accuracy vs. Precision, and Error vs. Uncertainty
AccuracyPrecisionErrorUncertaintyAccuracy refers to the agreement between a measurement and the true or correct value. If a clock strikes twelve when the sun is exactly overhead, the clock is said to be accurate. The measurement of the clock (twelve) and the phenomena it is meant to measure (The sun located at zenith) are in agreement. Accuracy cannot be discussed meaningfully unless the true value is known or is knowable. (Note: The true value of a measurement can never be known.)Accuracy refers to the agreement of the meas..See more on bellevuecollege

Accuracy is the agreement of a measured value with the actual value. Precision is the degree of agreement between several measurements of the same quantity or item. The uncertain digit is a digit..
Accuracy, Error, Precision, and Uncertainty
The precision of a measurement is usually indicated by the uncertainty or fractional relative uncertainty of a value. Repeatability is simply the precision determined under conditions where the same methods and equipment are used by the same operator to make measurements on [PDF]

ACCURACY, PRECISION AND UNCERTAINTY 2 If the true value was not as important as the magnitude of the value, you could say that the key’s length was 6cm, give or take 1cm. This is a crude estimate, but it may be acceptable. A better estimate of the key’s length, as you saw in Appendix A, would be 5. This tells us that the worst
