Question

Quizplus · Accepted Answer

Attribute control charts involve counting the number of defective units in a sample, while variable control charts measure the actual values of a characteristic. Since attribute charts are based on discrete data, they require larger sample sizes to ensure statistical validity and accuracy. Variable control charts, on the other hand, can often use smaller sample sizes since they are based on continuous data.
