ASN Curve - Average Sample Number Curve
The ASN curve shows the average number of units inspected (y-axis) for different incoming qualities (bottom axis). For single sampling plans the ASN is a constant so the ASN curve is a straight across line. However, for double sampling plans the ASN changes depending on how likely it is that the second sample is selected. When examining the ASN curve it is important to concentrate on that part of the curve that corresponds to the process average.
