acceptance sampling

In quality control, the statistical procedure employed in determining whether to accept or reject a production batch. If the proportion of the units having a certain negative characteristic exceeds the acceptable limit for a given batch, it is rejected. Two types of acceptance sampling are (1) Attributes sampling, in which the presence or absence of a characteristic in the inspected item is only taken note of, and (2) Variable sampling, in which the presence or absence of a characteristic in the inspected item is measured on a predetermined scale.
