Complementary Statistical Methodology for Precision and Bias Determination of Test Methods from Collaborative Studies on Analysis of Solutes in Water Cited in ASTM Standard Practice D 2777-86
Goddard MJ, Malaiyandi M

Abstract
ASTM Standard Practice D 2777-86 provides simplified numerical methods for the statistical analysis of collaborative tests of chemical assays. Herein, we discuss the critical assumptions underlying the statistical methods in the standard practice. Further statistical analyses are discussed to indicate additional information which may be obtained through a more rigorous statistical treatment.

Keywords:
quality assurance, bias, precision, water quality
