Description Readers' comments

In Sections 2 and 3 of the present note, starting from the relations obtained in Part I between the first-order indices (mean difference, simple mean deviation, and probable deviation), some graphical representations are used in order to: 1. define the range of the aforementioned indices, by considering the features of the considered sequence of values; 2. point out the reasons for their discordance and measure the possible degree of their discordance. In Section 4 the results obtained in Part I are used, again, to study the range and the main features of the quadratic mean deviation.
