Quizplus · Accepted Answer

When using both an R chart and a control chart to control a manufacturing process, the R chart should be analyzed first and brought into statistical control before preparing the control chart. This is because the R chart measures the variability within a sample, and if there is too much variability, it can affect the results of the control chart. Therefore, the R chart should be stabilized before moving on to the control chart. Choice A is the only option that lists the R chart first and the control chart second. Choice B does not include the R chart at all.
