Which concept involves sampling rather than inspecting all items?

Explanation:
Sampling to judge quality instead of inspecting every item is statistical sampling. The idea is to select a representative subset from a batch, examine those items, and use the results to estimate the overall quality and decide if the lot meets requirements. This approach saves time and resources while still providing a defined level of confidence, as long as the sampling plan specifies how many items to sample, how they’re chosen, and the acceptance criteria. Random sampling is a common technique within this concept, used to avoid bias in selection. 100% inspection would involve checking every item, which is not sampling, and process control focuses on monitoring and guiding the production process rather than making batch-acceptance decisions based on a sample.
