A Beginner's Guide to Uncertainty of Measurement (original) (raw)

The ,aim of this ,Beginner’s Guide is to introduce ,the subject of measurement uncertainty. Every measurement,is subject to some,uncertainty. A measurement,result is only complete,if it is accompanied ,by a ,statement of the ,uncertainty in the ,measurement.

Such uncertainties can be estimated using statistical analysis of a set of measurements, and using other kinds of information about the measurement,process. There are established rules for how to calculate an
