Sumario:Measurement and mathematical treatment of data are recent phenomena, to which human beings are not evolutionary programmed; this partly explains that many researchers, including those of science of men find the basic statistical notions difficult as well as the rejection to the quantitative analysis and the abundance of inadequate interpretations of statistical results. From the case of Gini index and of several coefficient of correlation, the article exhibits the deficiency of simplified recipes for the appropriate interpretation of these measures. The need of a sufficient comprehension of the mathematical properties of measures in order to be able to interpret them correctly is displayed and a minimum of familiarity with an ample scale of results of the application of a measure is emphasised as a vital condition for the appropriate use of it.
