ABOUT THE BOUNDS OF SEVERAL STATISTICAL INDICATORS

摘要

Statistical indicators play a very important role in the characterization of the various processes: economic, social and technological. In statistics, by general notion of scattering (variance or dispersion) refer to the individual values of measurable deviations from the central value. In the present paper we will obtain some properties of bounds of the variance, the standard deviation, the coefficient of variation and of the covariance related to several statistical indicators for discrete random variables in finite case. The results are developments of the research presented in [12].
