Combining the Results of Measurements,Measurements of the same quantity are often performed in different laboratories and, therefore, under different conditions and by different methods. Sometimes there arises the problem of combining these measurement data to find the most accurate estimate of the measured quantity.

Book 2017Latest editione measurement accuracy and recommendations on how to calculate systematic error of multiple measurements. There is also an extended section on the method of reduction, which provides an alternative to the least-square method and the method of enumeration. Many sections are also rewritten to improve

Statistical Methods for Experimental Data Processing, for measurement results. The realization of the random error in a given act of measurement is called the random error of a separate measurement, and the word “separate” is often omitted for brevity. Where it can cause confusion between a separate measurement and a complete measurement (which may co

Indirect Measurements,related to the measurand by some known relation. These other quantities are called . or, briefly, .. Among examples of indirect measurements, we can list measurement of the area of a plot of land presumed to have a rectangular shape (obtained from length measurements of the sides of the plot), measu

Combined and Simultaneous Measurements,equation. In either case, a measurement experiment involves multiple measurements, with each individual measurement producing one equation instance. Typically, the number of measurements is such that there are more equations than the unknown parameters and measurands. Because of measurement errors,

Examples of Measurements and Measurement Data Processing, measurement. We shall study two examples of such measurements with a Class 1.0 pointer-type DC voltmeter that operates using the energy of the source of the voltage being measured. Note that the energy consumption by the voltmeter causes interaction between the voltmeter and the object under study.

The International Vocabulary of Metrology and the Guide to the Expression of Uncertainty in Measurehe International Vocabulary of Metrology (VIM). The first such dictionary – “International Vocabulary of Basic and General Terms in Metrology” appeared in 1984. In 1993 came out the second edition of this document, and in 2007 the third (and current) edition. All three editions were prepared under t
