Statistics Help Evaluate Analytical Methods
The literature of analytical chemistry is filled with methods which were well conceived experimentally but were poorly evaluated. Many of the difficulties experienced in interlaboratory test programs are caused by such methods. Proper description of the capabilities of an analytical method requires the use of objective rather than intuitive data analysis. Some objective evaluation procedures will be described with emphasis on the concepts and their relationship to the best means of data collection.
