Question

Quizplus · Accepted Answer

An "out of control" process indicates that there are special causes present in the data, which are variations that can be attributed to a specific factor or event that is not part of the usual process. This is in contrast to common causes, which are variations that are inherent to the process and are expected. The presence of random variation or variation around the mean does not necessarily indicate an out-of-control process. Therefore, the best choice is B.
