Quizplus · Accepted Answer

Assignable cause variation is also known as special cause variation, which means it is caused by a specific identifiable source or reason that can be eliminated or controlled. This is in contrast to common cause variation, which is inherent in a process and cannot be easily attributed to a single cause. Random variation refers to fluctuations in a process that are unpredictable and cannot be attributed to a specific cause. Within-group variation is a term used in statistical analysis and does not specifically refer to assignable cause variation.
