摘要

This paper introduces four kinds of non-parametric statistical methods into textile material quality management and evaluation process. We present the sign test, rank sum test, poor logrank tests and poor range of two sets of data subgrade test in details and compare their advantages and disadvantages in different aspects of the application. We also illustrate the four tests with specific examples in textile material quality testing process and quality management process, and get some convincing results.
