Preferred Label : sampling error;
IUPAC definition : That part of the total error (the estimate from a sample minus the population value)
associated with using only a fraction of the population and extrapolating to the whole,
as distinct from analytical or test error. It arises from a lack of homogeneity in
the parent population. In chemical analysis, the final test result reflects the value
only as it exists in the test portion. It is usually assumed that no sampling error
is introduced in preparing the test sample from the laboratory sample. Therefore,
the sampling error is usually associated exclusively with the variability of the laboratory
sample. Sampling error is determined by replication of the laboratory samples and
their multiple analyses. Since sampling error is always associated with analytical
error, it must be isolated by the statistical procedure of analysis of variance.;
