Quizplus · Accepted Answer

The $ \bar{x} $-chart is used to monitor the centering of the process, by plotting the sample mean of the process over time. It is an effective tool for detecting any shifts in the process mean, which may indicate a need for corrective action. The R-chart, p-chart, and np-chart are all used for monitoring the variability of the process or the proportion of nonconforming units, and are not as suitable for monitoring centering.
