Sampling practice and theory - Mine Engineer.Com
Sampling is defined as taking a small portion of a whole mass that accurately represents the whole mass. Very simple to define, however obtaining a representative sample is anything but simple. Mathematicians will say sampling is expressible as a series of mathematical equations. Such as, for sampling "X" pounds of material, one would take "y ...
