It is used, along with significant digits, to indicate the precision of a measurement. Thus, in the two-significant-digit measurement 5.4 0.2 meters, the uncertainty interval is 0.2 meters. This means that the true value of the measurement is believed to lie between 5.2 meters and 5.6 meters.
Precision is defined by the repeatability of the instrument and is normally expressed as a standard deviation. This is also known as Type A data for measurement uncertainty analysis. Resolution: Smallest change in a quantity being measured that causes a perceptible change in the corresponding indication. Resolution can depend on, for example, noise (internal or external) or friction. It may also depend on the value of a quantity being measured. Resolution of a displaying device is the smallest difference between displayed indications that can be meaningfully distinguished.
