Sampling Distribution of the Coefficient of Variation when the Population Takes Normal Distribution <i>N</i>(<i>0,σ2</i>)

Abstract

The coefficient of variation of the raw silk size objectively expresses the fluctuating characteristics of the raw silk size, and is an important quality index in the development of the new standard used in the electronic testing for raw silk. This paper theoretically deduces the sampling distribution of the coefficient of variation of the normal population, justifies the theoretical results by computer simulation using Monte Carlo method, and thus afford important theoretical basis for the development of the new standards for the electronic testing of the raw silk size.
