All one would have to do would be to lie the pencil next to the ruler and see where the pencil falls with regard to the measurement marks. Take for example, someone attempting to measure a pencil using a ruler. This is for the simple reason that one cannot be infinitely precise or accurate. Where does measurement uncertainty come from?Īll measurements are subject to measurement uncertainty. #MICROSCOPE RESOLUTION CALCULATOR HOW TO#Understanding and knowing how to limit measurement uncertainty is key to reconciling these two competing factors. Nonetheless, industry leaders and researchers still often desire microspheres of only one very specific size. The reasons for why this is are explored in the next section. Why is measurement uncertainty important? The “ Guide to the Expression of Uncertainty in Measurement,” or GUM for short, is the generally accepted guide to all things measurement uncertainty related. Precision should not be confused with accuracy, which is “the closeness of agreement between a measured value and the true value.” (NDT Resource Center). ![]() Here, precision is defined to be “the closeness of agreement between independent measurements of a quantity under the same conditions.” (NDT Resource Center). even the ones that you didn’t know you had.Īccording to the International Vocabulary of Metrology – Basic and General Concepts and Associated Terms (VIM) 3rd edition, prepared by the Joint Committee for Guides in Metrology, measurement uncertainty is defined to be a “non-negative parameter characterizing the dispersion of the quantity values being attributed to a measurand, based on the information used.” Here, a quantity value is defined to be a “number and reference together expressing magnitude of a quantity,” and a measurand is defined to be the “quantity intended to be measured.” In layman’s terms, measurement uncertainty can be said to be how precise a measurement is, or alternatively, how confident we can be that a measurement is a certain value. It is hoped that after reading this article, all your questions regarding measurement uncertainty will be answered…. This article contains a comprehensive guide on what measurement uncertainty is, where it comes from, how it is calculated, and how it applies to both yourself and to Cospheric. Have you ever wanted to understand what measurement uncertainty is and how it applies to Cospheric microspheres? If you have, then this article is what you have been looking for.
