Development objectives

The course objective is to provide a quantitative analysis methodology based upon observation, findings and elaboration of collective phenomena. In particular the problematics of analyzing data will be discussed, as well as the design and creation of surveys and experiments in diverse applica-ble sectors for descriptive, interpretational and decision-making ends.

Statistics and its applications: content and applications of statistics, the origin and the evolution of statistics, the statistical sources and the graphical repre-sentations.

The means: the arithmetic mean, the harmonic mean, the geometric mean, the square mean, the cubic mean and power means; the median, the other medium position: quartiles, percentiles quantiles; the mode; final comments.

The index numbers and other statistical reports: the comparison of statistical data, statistical reports, indices ratios, the based fixed and mobile index num-bers, the change of the basis of the index numbers, the index numbers for the monetary adjustment.

The indices of variability: the variability; ranges of variation, the range, the difference range; difference from an average; the average of the deviations, the average of the squares, the variance, the variance of a linear transforma-tion, of the sum of variables, of groups of variables; standardization; relative indices of variability.

The study of relations between phenomena, the phases of the analytical repre-sentation, the bivariate model, the method of least squares, the linear regres-sion, the linear correlation coefficient, other considerations about the linear correlation coefficient, the regression line in the weighted distributions, the co-efficient of determination, the significance of the linear correlation coefficient.

Relations between mutabilities, the observed distribution of two phenomena, distribution theory, the comparison between the observed and the theoretical model, a measure of the connection.
