Quizplus · Accepted Answer

Assignable variations are caused by specific events or factors that are often temporary, such as machine malfunctions or operator errors. These variations can be traced back to a specific cause and can be eliminated or controlled. Chance variations, also known as random or common cause variations, are inherent in any process and cannot be eliminated completely. Out of control variations refer to any variation that falls outside of the control limits and indicates that the process is not in a state of statistical control.
