- General introduction to the statistical method.
- Preliminary definitions and glossary.
- Type of statistical characters and their properties.
- Tables and frequency distributions.
- Graphical representations.
- Measures of centrality and dispersion.
- Contingency tables, independence and measures of association.
- Correlation and linear regression.
- Probability: definitions, basic concepts and theorems.
- Conditional probability. Independence.
- Random variables (discrete and continuous), probability and distribution functions and expected values. Linear combinations of random variables.
- Sampling and sampling distributions.
- Pointwise estimation and interval estimation for the mean, for the variance and for the proportion of a population.

At the end of the course the students will be able to:
- address and propose solutions to simple problems of economic nature on the basis of the information contained in the available data and duly summarized through appropriate statistical analysis techniques;
- be able to analyze a data set with the software R.
The course holds almost everywhere an introductory level and requires only the knowledge of a basic course in Mathematics.
The course consists of lectures in lab mode with discussion of techniques of analysis, examples of practical analysis and contextual applications on real data.
The final exam consists in solving theoretical and applied exercises supported by the use of the softare R.
