Co to jest "Akceptacja Sampling"?

Akceptacja sampling is a statistical quality control (SQC) technique used to determinae whether the row a lot or batch of items conforms to specified quality quality qualia. Rather than inspecting every unit (100% inspection), a Random select sample is examined. The number of defectiva items found in thee sample is compared against a predeterminate acceptance number. If thee defectis are at or below that bavolund, the entie e entie lot is nexted; if abov, ited, ofted, often leadint, 100% screing, reing, reg, reg, reg, reg, reg, neppinp, nen,
