The Statistical Comparison of Measuring Instruments. (A Study of Precision and Accuracy Problems for NATO Velocity Measuring Chronographs)

Abstract

The problem discussed and solved here is that of determining whether the precision and accuracy of a velocity measuring chronograph is suitable for general use. The study arose in connection with the need to compare a 'test' chronograph of one of the NATO countries with that of two NATO 'standard' chronographs, in order to ascertain whether the 'National' instrument submitted for acceptance may be used as an approved chronograph for measuring velocities generally. Since the methodology developed herein covers both the estimation problem and the various statistical tests of significance required on variances in errors of measurement (or imprecision), as well as tests on accuracy, then the results are believed to be of rather wide applicability.
