Abstract
A prototype of a computerized system has been developed to automatically acquire, statistically test and supply the parameters needed (standard deviation and percent recovery--obtained by running control samples) to compute 95% confidence intervals for chemical (and other) measurements contained in an organizations’s main database (or locally) and ultimately to unbias those measurements and their confidence intervals. All sources of stochastic variation within the analytical methods are characterized, manipulated and corrected so as to provide parameters that are truly representative of the stochastic processes that occur in each individual analytical method as it is being done in a particular laboratory. This is done by running chemical, biological, microbiological or radiological control samples on specially designed computer spreadsheet forms over several analytical runs that automatically test the data statistically as it is being accumulated. These forms and their control samples are often suitable to be continued to be run for quality assurance purposes after their respective parameters have been obtained. The entire computerized system could be adapted and operated from a particular internet website making it available to fee-paying subscribers all over the world.
