Uncertainty Measurement

Uncertainty of measurement is the doubt that exists about the result of any measurement. You might think that well-made rulers, clocks and thermometers should be trustworthy, and give the right answers. But for every measurement – even the most careful – there is always a margin of doubt.

Standard deviation

Author: GaugeHow Team

Example of Standard Deviation: Suppose you have a set of n readings Start by finding the average:Consider the set of readings 16, 19, 18, 16, 17, 19, 20, 15, 17 and13, the average is 17.Next, find the difference between each reading and the average, i.e. -1 +2 +1 -1 0 +2 +3 -2 0 -4,and […]

Coverage factor

Author: GaugeHow Team

Usually, standard uncertainty referred by 68% and Expected uncertainty is 95% if we assume a normal distribution. We can create our desire coverage interval as below. case-1 For coverage interval ‘u’ coverage probability is 68% in this case, we multiply to standard uncertainty by 1 here one is coverage factor case-2 For coverage interval, ‘2u’ […]

How to calculate uncertainty?

Author: GaugeHow Team

To calculate the uncertainty of a measurement, firstly you must identify the sources of uncertainty in the measurement. Then you must estimate the size of the uncertainty from each source. Finally, the individual uncertainties are combined to give an overall figure. The two ways to estimate uncertainties No matter what are the sources of your […]

Standard and Expanded uncertainty

Author: GaugeHow Team

Standard uncertainty All contributing uncertainties should be expressed at the same confidence level, by converting them into standard uncertainties. A standard uncertainty is a margin whose size can be thought of as ‘plus or minus one standard deviation’. The standard uncertainty tells us about the uncertainty of an average (not just about the spread of […]
