Statistical Engineering Division, National Bureau of Standards, Gaithersburg, MD 20899 Statistical Concepts in Metrology" was originally written as Chapter 2 for the Handbook of Industrial Metrology published by the American Society of Tool and Manufacturing Engineers, 1967. It was reprinted as one of 40 papers in NBS Special Publication 300, VolUlUe I, Precision Measurement and Calibration; Statistical Concepts and Procedures, 1969. Since then this chapter has been used as basic text in statistics in Bureau-sponsored courses and seminars, including those for Electricity, Electronics, and Analytical Chemistry.
While concepts and techniques introduced in the original chapter remain valid and appropriate, some additions on recent development of graphical methods for the treatment .of data would be useful. Graphical methods can be used effectively to "explore" information in data sets prior to the application
of classical statistical procedures. For this reason additional sections on statistical graphics are added as a postscript.Key words: graphics; measurement; metrology; plots; statistics; uncertainty.
