Understanding the Double Sampling Plan: A Comprehensive Guide
Definition & meaning
A double sampling plan is a method used in statistical quality control. It involves taking two separate samples from a lot of items to make a decision about the entire lot. The first sample is examined, and based on the results, a decision is made to either accept the lot, reject it, or take a second sample for further inspection. The total sample size combines both samples to determine the final outcome.
