For example, if the mean is [[mu].sub.t] = 6.4, then the standard deviation is 2.5298 and the upper control limit is 13.99, leaving a probability of
Examination of the three control charts from exam 1, exam 2 and exam 3 reveals that the Upper Control Limit has reduced from 0.313 to 0.305 to .207, the Centerline has reduced from 0.194 to 0.188 to .112 and the Lower control Limit has moved from 0.076 to 0.071 to .017.
Additionally, the standard deviation of the transformed data was on the same order as the mean of the transformed data, resulting in a very wide upper control limit when the charts were replotted back in the original moisture content units.
Only 10 percent are seen beyond the upper control limit. The "Late" phenomenon becomes more critical as scheduling density increases.
The first check of the data should be determining that the range of the three trials of any sample for each appraiser does not exceed the Upper Control Limit of Range (UCLR).
The process of establishing the Upper Control Limit (UCL) and Lower Control Limit (LCL) deviated from the usual practice of using the overall average plus or minus three standard deviations.
A batch plot above the upper control limit, or below the lower control limit, indicates some kind of manufacturing process change has occurred due to more than just chance.
For example, suppose that the first point and every sixth point thereafter (as in Figure 4) falls above the upper control limit on the control chart of a particular preparer.
The p, x and R center lines are past averages of the process and the upper control limit (UCL) and lower control limit (LCL) are simply three standard deviations from the center line (Figure 4).
The control chart based on (1) has an upper control limit which is determined with a percentile of chi-square distribution.
Hence, the control limits which are the upper control limit (UCL) and the lower control limit (LCL) are calculated for the I-MR charts.
where UCL = the upper control limit; LCL = the lower control limit; X = the process average; [sigma] = the process standard deviation; [lambda] = the weight factor, 0 < [lambda] [less than or equal to] 1.
