In many analytical laboratories, the choice of analytical method is frequently dependent on the equipment available. For most analyses, there are a number of different approaches to the problem of determining the composition of a sample, but generally the analyst uses one consistently, either from personal preference or from lack of proper equipment to use other methods. He therefore depends on the accuracy and precision of the one method, with, perhaps, some reservation given in accordance to the limitations as stated by the author of the procedure. It will be the purpose of this thesis to set forth a statistical analysis of four commonly used methods of copper determinations with the view in mind of ascertaining the relative merits of each method, the limitations, and just what one can expect in the way of precise results when employing the procedures.
