The degree to which a property or a
constituent is uniformly distributed throughout a quantity of material. A material may be homogeneous
with respect to one analyte or property but heterogeneous with respect to another.
The degree of heterogeneity (the opposite of homogeneity) is the determining factor
of
sampling error.
