Question

Quizplus · Accepted Answer

Assignable cause variation is also known as special cause variation. This type of variation is caused by factors that are not inherent to the process, but instead come from outside sources such as a broken machine or human error. It is distinct from common cause variation, which is a result of factors that are inherent to the process and is typically characterized by a stable, predictable range of outcomes. Controlled variation refers to the ability to manage and minimize variation within a process. Random variation is another term for common cause variation. Therefore, the best answer is B, special cause variation.
