Average range

To construct the control chart, ranges for a minimum of 15-20 samples (preferably 30 or more samples) are obtained while the system is known to be in statistical control. The line for the average range, R, is determined by the mean of these n samples... [Pg.717]

The average range for the 20 duplicate samples is 0.177. Because two replicates were used for each point, the UWL and UCL are... [Pg.718]

For a discussion of this important performance control topic, refer to Cylinder Unloading, later in this chapter and Figure 12-27. A reasonable average range is 7-22% with fixed valve pockets. ... [Pg.422]

Use the preliminary table until data are acquired during the sampling. As the analyses proceed, the results are combined with those from previous studies. When approximately fifteen pairs O) of results are acquired from the particular study area, a new table should be calculated based upon the average range of the data that has been accepted to date. [Pg.100]

The statistical uncertainties in these processes are reflected in "straggling", a term which describes the variations in the number of collisions undergone by any one particle and the amount of energy transferred at each collision. There is a corresponding variation in the penetration or range of particles in a material. One MeV electrons have an average range of 4.3 mm in unit density material. [Pg.15]

Shrinkage and coefficient of thermal expansion are in a rather low or average range for a polymer, depending on the rubber content. The absorption and alteration by moisture exposure are low. [Pg.357]

Figure 10.2 Statistical process control charts for clearings. Top panel runs chart showing clearings as a function of measurement number. Middle panel x-bar chart with dashed upper control limit (UCL) and lower control limit (LCL) solid horizontal line is the grand mean, X. Bottom panel range chart with dashed upper control limit (UCL) solid horizontal line is the average range, r. Figure 10.2 Statistical process control charts for clearings.
