Two-Sample Tests for Comparing Measurement Systems

Summary: In some situations, two different types of measurement systems have been developed to measure the same quality characteristic on a product. In this scenario, one might be interested in comparing the ability of the two systems to provide precise measurements as quantified by measurement systems analysis criteria. To allow such comparisons, this article provides two-sample hypothesis tests for five different measurement systems analysis (MSA) criteria. The techniques are demonstrated using data from an automotive body manufacturing facility that compares a coordinate measuring machine to a noncontact vision-based measurement system.
