Sampling with and without replacement.
If we randomly sample n distinct items from a Population of N items, this is simple random sampling without replacement. This is what is typically done in SPC.If each time we randomly sample one item at a time return it, randomly sample another, etc., this is sampling with replacement. From a theoretical standpoint, this mimics sampling from an infinite (or hypothetically infinite) population.A hypothetically infinite population could be all future production of a type of part, or it might be all future transactions of a certain type.
