Sampling and subsampling diagrams provide a means of visualizing and controlling sampling error during analysis of mixtures, especially those in which a minor constituent contributes heavily to assay values. The model employed refers each sampling problem to an idealized mixture of two constituents which has the same sampling or subsampling characteristics as the real mixture to be sampled. A procedure for calculating and constructing such diagrams depends on appropriate use of both Gaussian and Poisson statistics. The argument is simplified by combining the two statistical models.
