Sampling Inspection involves
inspecting a relatively small number of
items from a batch or lot and then using
the results of this sample to either accept
or reject the entire lot. The accept/reject
criteria is the number of defective items
found in the sample.
Sampling inspection relies on statistical
probability and it is possible that a good
batch will be wrongly rejected, or a bad
batch will be wrongly accepted. This can
have significant economic consequences and
so it is usual to use a published sampling
plan, such as ANSI/ASQ Z1.4-2003.
