Question

Quizplus · Accepted Answer

A process is considered stable when there is only random variation present. Nonrandom variation, also known as assignable variation, indicates that the process is out of control and there are specific factors causing the variation. Therefore, option A is incorrect as some variation should be present in any process. Option C is incorrect because nonrandom variation should not be present in a stable process. Option D is incorrect as one of the options must be correct.
