Representativeness
Definition
A description of how closely a sample reflects the characteristics of the whole. Although challenging to verify, effort should be made to ensure that a sample is representative using techniques such as thorough mixing to obtain homogeneity, duplicate analyses, etc.
Definition and Description
Representativeness in the context of sampling refers to the degree to which a sample accurately mirrors the characteristics of the entire population or source from which it is drawn. It is the extent to which the sample provides a reliable and unbiased reflection of the whole. Achieving representativeness is crucial in sampling procedures and is often ensured through methods like thorough mixing to achieve homogeneity and conducting duplicate analyses. The goal is to minimize sampling errors and biases to obtain a sample that faithfully represents the broader population or source.
