Question

Quizplus · Accepted Answer

Assignable variation refers to variations in a process that can be attributed to specific, identifiable causes, such as defects in a machine, an operator error, or environmental factors. This type of variation can be corrected or eliminated through targeted improvements, making it important to identify and address in order to improve process performance. Chance variation, on the other hand, is inherent to any process and involves random factors that are not easily controlled or predicted. Common variation refers to the aggregate effects of chance variation, which tend to occur consistently over time and can be characterized using statistical techniques such as control charts. While all three options are true, C is the best choice as it specifically addresses the type of variation that can be addressed and improved through specific actions.
