Abstract: The paper „The Synthetical Indicators of Variability. An Approach in Tourism” develops the variability of frequencies distributions and the statistical methods of analysis of it. Among these are included the estimation and the analysis of synthetical indicators of variability which are: the average linear deviation, the standard deviation, the dispersion and the coefficient of variation. These indicators measures the degree of variability of individual items of frequencies distributions in comparis on with an indicator of central tendency, as a rule the average and sometimes the median. In the analysis of dispersion, the standard deviation is finding the application also in the Chebyshev’s theorem and in the empirical rule, enunciated in the paper. I n the case of multidimensional distributions the total dispersion results as a sum of dispersions (the group dispersion and the dispersion between groups) under the form of rule of addition the dispersions. The paper presented a concise study of tourism in Romania in 2005, using the dispersion indicators in the analysis of travel duration, in the case of internal travels of the residents for vacations and business, on the touristic zones.
