Understanding 抽样 (Sampling)

The term 抽样 (chōuyàng) refers primarily to the process of selecting a subset from a larger population or batch for analysis or inspection. It is widely used in statistics, quality control, and research contexts.

Usage and Context

When speakers use 抽样, they often imply a methodical selection to represent the whole, such as in surveys or product inspections. It is a technical term and appears frequently in scientific, industrial, and academic discussions.

Common Collocations

  • 抽样调查 (sampling survey): used in research to collect representative data.
  • 抽样检验 (sampling inspection): quality control process to check product batches.
