Statistical procedure used in quality control. Acceptance sampling involves testing a batch of data to determine if the proportion of units having a particular attribute exceeds a given percentage. The sampling plan involves three determinations: (1) batch size; (2) sample size; and (3) maximum number of defects that can be uncovered before rejection of the entire batch. This technique permits acceptance or rejection of a batch of merchandise or documents under precisely specified circumstances.
Acceptance sampling is a valuable tool often used (and misused) in the manufacturing sector. The most common methods employ standards so you can look up a sampling plan. The user has many choices, and needs to understand their impact on cost and risk. This seminar explains how to apply Z1.4 and c=0 plans.
