We all want the clothes that we manufacture to be one hundred percent perfect in regard to quality. However, it is very time consuming and costly to complete full quality testing on every single garment produced. This is why the majority of companies will utilize some sort of statistical sampling method.
If we flip a coin one time, the odds of the coin landing on heads is 50%.
If we flip the same coin ten times, it is actually unlikely that we will get exactly 5 heads and 5 tails.
But if we flip that coin thousands or tens of thousands of times we know that approximately 50% of the time the coin would land on heads.
This is the principle of statistical auditing. The statistical projections from a relatively small sampling are accurate enough to serve as a workable standard for a large number of instances. Therefore, if we have a shipment of 10,000 T-shirts (being produced in one factory), we can for example check the quality of portion of the order to determine if a quality concern exists. Certainly the system is not perfect, but doing the statistical audit is often the best option.
