The first step in any chemical analysis is to obtain a representative sample to measure in a process called <u>sampling</u>.
Sampling is the process of choosing a subset of people (a statistical sample) from a statistical population in order to estimate the entire population's characteristics. It is used in statistics, quality control, and survey technique. Statisticians try to get samples that are typical of the population under investigation. In situations when it is impractical to assess the complete population, sampling offers insights and is more affordable and quicker than doing so.

<u>Random Sample</u>
