The main aim of the course is to introduce the logic and the basic concepts of statistics, with particular attention to the applications in the fields of economics and business administration. Specifically, the course focuses on univariate and bivariate descriptive statistics, but it also provides an introduction to time series analysis and to inferential statistics. The applications regard real data, the presentation and discussion of results.

I Introduction to Statistics

• Statistics: definitions
• Statistics in the framework of empirical research
• The operationalisation of concepts
• From properties to variables, from the units of analysis to cases
• The data matrix
• Types of variables
• Statistical data and data collection
• Official statistics

II Univariate analysis

• Frequency distribution
• Measures of central tendency
• Measures of variability
• Robust measures of central tendency and variability
• Concentration
• The shape of a distribution (symmetry, kurtosis and normal distribution)
• Graphical representation

III Introduction to time series

• Simple and multiple time series
• Fixed base index numbers
• Chain base index numbers
• Rate of annual change
• Composite index numbers
• The components of a time series
•  

IV Bivariate analysis

• Measures of relationship between two variables
• Contingency tables
• Relationships between quantitative variables

V Regression

• Exploration, description, explanation
• The regression model
• Linear regression
• The ordinary least square method
• Total variation, explained variation, residual variation
• Coefficient of determination
• Interpolation in the case of time series

VI Introduction to inferential statistics and statistical sampling

Mathematics

• Knowledge and understanding: at the end of the course students must have acquired the knowledge of the basic concepts of statistics, with particular reference to the techniques of univariate and bivariate analysis. Educational methods used to reach these goals: frontal lectures, exercises, class discussion.
• Applying knowledge and understanding: the students must be able to identify and apply appropriately, to real research and analysis situations, the concepts, the techniques presented throughout the course. In particular, they must be able to apply the acquired knowledge in the fields of economics and business administration. Educational methods used to reach these goals: frontal lectures, exercises, class discussion.
• Making judgements: the students must be able to link concepts presented throughout the course, to deal with complex problems independently, to make judgements and critical reflections. Educational methods used to reach these goals: exercises and class discussion.
• Communication skills: the students must be able to clearly and incisively communicate, appropriately using the lexicon of statistics. Educational methods used to reach these goals: exercises and class discussion.
• Learning skills: the students must develop adequate learning skills, so as to be able to extend and deepen the knowledge acquired throughout the course, following new paths of research and analysis and acquiring new knowledge. Educational methods used to reach these goals: frontal lectures, exercises, class discussion.

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
