Explanation

Sampling is the practice of selecting a representative subset from a larger population when it is impractical, too costly, or impossible to collect data from every individual. The goal is to draw statistically valid conclusions about the entire population based on the sample. Collecting without interference describes controlled experimentation, not sampling. Automating the extraction process is a data engineering concern. Asking many individuals a series of questions describes a survey, which may use sampling as a method but is not the definition or reason for sampling itself.
