Example text

When there are k sets of n data, then: _ A: R = (l/k)lRj where Rj is the range of thejth set of data. 6. 27. R is used less often than s, because it is more vulnerable to extreme values. However, in routine work, for instance in quality control, and for small samples it is used rather often. 6 Computation of the average range for a characteristic of a product. Four replicates of each sample are measured. 1 Quality and errors Quality assurance has been defined [8] as a system of activities whose purpose is to provide the producer or user of a product or service with the assurance that it meets defined standards of quality with a stated level of confidence.

This is often not the case in practical situations. Systematic errors are propagated with their signs. 28) where Axi, etc. are the systematic errors affecting x\, etc. While random errors do not compensate but accumulate, systematic errors can compensate. 29) 44 In eq. 29) we observe that for this type of relationship relative systematic errors are transmitted. Equations of the type described in this section have assumed a large importance in metrology, because they allow us to describe individual sources of error and to combine them to describe what is called in metrology language the uncertainty.

74% of the objects fall inside the tolerance intervals. It is customary to evaluate Cp as follows: - Q? 33: reliable or stable situation. However, some companies require Cp to approach 2. By requiring such strict control on variability shifts in setting may occur without immediately causing values to fall outside the tolerance intervals (see further). 33 > C/7 > 1: control of setting required. 67: unacceptable. 22. This process would be qualified as requiring control. Another index of dispersion is the relative precision index (RPI).
