Title: The need for sampling, rather than 100% checking
Post by: Tanvir Ahmed Chowdhury on June 09, 2014, 12:37:44 AM

When controlling the quality of a batch of products, it is not practical to inspect 100% of them (unless the quantity is very small). Inspecting a large number of products takes a long time: it is expensive, and inspectors are less effective as they get tired. Actually, a 100% check does not yield that much more information than inspecting a statistically representative sample.
