Learning outcomes

The course aims to provide a methodology of quantitative analysis based on observation, collection and processing of collective phenomena. In particular, the issues are treated on analysis of data, the design and construction of in-vestigations and trials in different sectors, for descriptive, interpretative and decision-making purposes.

Program

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.
