Key Points: Attribute measurements are those quality characteristics that are classified as either conforming or not-conforming to specifications. Proportion (p) and c-charts are used for attribute measurements. Mean and range charts are examples of variable measurements. In variables sampling, we measure the actual weight, volume, or other variable measurements.
