Segalove, Running Standards in Clinical Chemistry and the Use of the Control Chart
A control chart
is used to monitor the behavior of a given process.
Pareto charts, histograms, and control chart
use may also point to significant causes.
They also explain which type of control chart
is most applicable to a particular process and they complement BS 5702-1:2001--Guide to statistical process control (SPC) charts for variables.
Though the ISRT attribute control chart
plots a square root transformed statistic rather than the statistic of interest, the link between the plotted statistic and the statistic of interest is simple to be interpreted.
This point is important and will be used in the development of a control chart
It should be noted, however, that a control chart
indicating a process is in control does not necessarily assure the process will produce quality output.
There are different kinds of control chart
Operators can right-click on any data point of interest and bring up a control chart
New pick lists and pop-up windows take users to a specific control chart
faster than the previous series of menus.
As we known, Shewhart control chart
is based on the supposition that the process is in stationary situation (Montgomery, 1991).
The configuration of a control chart
involves a centerline that represents the mean of the data set, and "control limits" that are calculated to represent [+ or -]3 standard deviations (or standard errors of the mean).
