Question

Quizplus · Accepted Answer

The increase in the number of defective parts is likely due to assignable variation, which is caused by specific identifiable factors such as the reprimand given to the employee. Common-cause variation refers to natural variation that is inherent in the process, while random variation is unpredictable and cannot be attributed to any specific cause. Homoscedasticity refers to the assumption of equal variance in a statistical model, which is not relevant to this scenario. Costs of attrition refer to the expenses involved in employee turnover, which is not directly related to the increase in defective parts.
