Hypernyms ("sampling" is a kind of...):
choice; option; pick; selection (the act of choosing or selecting)
Domain category:
statistics (a branch of applied mathematics concerned with the collection and interpretation of quantitative data and the use of probability theory to estimate population parameters)

Hyponyms (each of the following is a kind of "sampling"):
acceptance sampling (a statistical procedure for accepting or rejecting a batch of merchandise or documents; involves determining the maximum number of defects discovered in a sample before the entire batch is rejected)
random sample (a sample in which every element in the population has an equal chance of being selected)

An international team of researchers from the U.S. and France used a combination of methods to monitor the accumulation of mercury from the atmosphere, performing continuous sampling over a two-year period, including through the Arctic winter.

Many of the ejected particles are small enough to be collected by the spacecraft's sampling mechanism, meaning that the returned sample may possibly contain some material that was ejected and returned to Bennu's surface.

The technique used, called sub-sampling by interpolation, only acts to remove the pixelisation and make a smoother image, and it is important to note that the comet's surface features won't be as smooth as the processing implies.

Only the tiniest sample needs to be provided, which seeps by capillary action from the sampling area to the recognition area, where a particular colour will appear, depending on the concentration of the compound being analysed.

The genome of the Zika virus had already been sequenced in 2016 by the Virology and Experimental Therapy Department of FIOCRUZ in Pernambuco in collaboration with scientists from the University of Glasgow, but human sampling was used back then.
