Correct sampling

During sampling of particulate materials, correct sampling is defined in Gy's sampling theory as a sampling scenario in which all particles in a population have the same probability of ending up in the sample ^[1].

The concentration of the property of interest in a sample can be a biased estimate, for the concentration of the property of interest in the population from which the sample is drawn. Although generally non-zero, for correct sampling this bias is thought to be negligible ^[1].
