Publisher Summary This chapter introduces the subject of measurement uncertainty, focusing on the importance attached to this subject. Measurement errors are impossible to avoid, although we can minimize their magnitude by good measurement system design accompanied by appropriate analysis and processing of measurement data.

Uncertainty and confidence in measurements [PDF]
IEE Uncertainties Workshop-Electrical Measurements, 1998 All measurements are tainted by imperfectly known errors, so the significance associated with the result of a measurement must account for this uncertainty. This paper explores the reasoning behind, and the requirements for, the expression of a value of uncertainty associated with a measurement result.

Journal of Chromatography A, 2007
Measurement uncertainty is a statistical parameter which describes the possible fluctuations of the result of a measurement. It is not a mere repeatability but it is at least as high as the intra-laboratory reproducibility. If it is an attribute of a general analytical test procedure it is at least as high as the inter-laboratory reproducibility ...

Studia Logica, 2009 Two types of measures of probabilistic uncertainty are introduced and investigated. Dispersion measures report how diffused the agent’s second-order probability distribution is over the range of first-order probabilities. Robustness measures reflect the extent to which the agent’s assessment of the prior (objective) probability of an event is perturbed

Consistency for uncertainty measures
International Journal of Intelligent Systems, 1998The problem of the consistency for the assessment of a set of data in the framework of nonadditive measures is considered. In particular, some cases are analyzed in the quantitative setting in comparison with classical probability assessments. An actual extension of consistency to belief and plausibility measures is developed.

Measuring Uncertainty in Orthopairs
2017In many situations information comes in bipolar form. Orthopairs are a simple tool to represent and study this kind of information, where objects are classified in three different classes: positive, negative and boundary. The scope of this work is to introduce some uncertainty measures on orthopairs.

Measurement, Models, and Uncertainty
IEEE Transactions on Instrumentation and Measurement, 2012Against the tradition, which has considered measurement able to produce pure data on physical systems, the unavoidable role played by the modeling activity in measurement is increasingly acknowledged, particularly with respect to the evaluation of measurement uncertainty.

Measurement, information and uncertainty
Mathematics and Computers in Simulation, 1987The issues discussed in this paper are probably best classified under the heading of epistemology, in that they concern the differences in the limitations of what can be known (observed) in the physical, social and biological sciences. The smooth, continuous processes described by Gaussian distributions in the physical sciences are contrasted with the ...

The Measurement of Uncertainty in Illness
Nursing Research, 1981The purpose of this investigation was to explore the role of uncertainty as a significant variable influencing patients' experiences in illness, treatment, and hospitalization. A theory was proposed on uncertainty in illness. Based upon this conceptualization, a 30-item scale tapping the uncertainty in symptomatology, diagnosis, treatment, relationship
