An OC (Operating Characteristic) curve shows the probability or chance of accepting a lot given various proportions of defects in the lot. It is widely used in statistical process control to determine the quality of a product or process. The curve plots the inspection sample size against the percent defective in the lot and shows the probability of accepting the lot. The shape of the curve depends on the sampling plan and the acceptable quality level (AQL).
