Page 36 - It is another matter to formulate specific statements regarding these statistical characteristics of measurement processes. 4.2. 1 Precision — Precision may be stated in terms of an index of precision of the form ±a, where a is some positive number. The numerical value of a in any such index of precision will be smaller the more closely bunched are the individual measurements of a process. However, any such index must have a clearly understandable interpretation regarding variability of measurements....
