uncertainty in measurementISO-GUMIt is imperative that the method for evaluating and expressing uncertainty in measurement should be uniform among scientists and engineers so that measurements performed in different scientific and technological fields can be easily compared. This article attempts to ...
When we measure things, most people are only worried about how accurate, or how close to the actual value, they are. Looking at the process of measurement more carefully, you will see that there is another important consideration: precision. Matt Anticole explains what exactly precision is and...

I used to be uncertain - now I#m not so sure. In ordinary use the word #uncertainty# does not inspire confidence. However, when used in a technical sense as in #measurement uncertainty# or #uncertainty of a test result# it carries a specific meaning. It is a parameter, associated with...
If a measurement is written as a best estimate plus/minus an uncertainty, this uncertainty is itself an absolute uncertainty. The measurement would most probably lie in the range of the best estimate plus/minus this uncertainty. The relative uncertainty is defined as the ratio of...
英文的意思是：根据人类的反应时间从开始到结束，时间间隔的测量用秒表通常有约0.2的不确定性 。如果要计算的话，你可以设定一个开始的时间和结束的时间， 实际的结束时间要考虑0.2秒的不确定性。我认为应该考虑两种情况：多0.2或少0.2秒。

The first step to selecting the right pressure calibration product is to understand the specifications of the device under test (DUT). Following is a summary of which products are used to calibrate different categories of DUTs, based on total one-year measurement uncertainty specifications (assumes ...
