Batch Testing
Batch Testing is a quality control method where multiple samples from the same production group or "batch" are tested together to ensure quality and consistency. This approach is commonly used in pharmaceutical, food, manufacturing, and chemical industries. Instead of testing every single item, which would be time-consuming and expensive, technicians test representative samples from each batch. Think of it like checking a few cookies from each baking tray to make sure the whole batch is good, rather than tasting every cookie.
