Which of the following is a common quality assurance technique in manufacturing?

Statistical sampling is a widely recognized quality assurance technique in manufacturing. This method involves selecting a representative sample from a larger population to evaluate the quality of products or processes. The purpose of statistical sampling is to make inferences about the quality of the whole batch based on the analysis of the sample. This approach is systematic and data-driven, allowing manufacturers to detect defects, monitor production quality, and ensure that the final products meet established standards without having to inspect every single item produced.

Using statistical sampling helps to efficiently manage resources, as it is often impractical or costly to conduct a full inspection of every item in a production run. By applying statistical methods, manufacturers can identify trends, control processes, and ultimately enhance the overall quality assurance efforts within their operations.
