OVERVIEW

The course “Statistics 1” aims to provide students with the main tools for the quantitative analysis of economic and social phenomena, and to supply the basic statistical knowledged needed to face the other quantitative courses of the Degree Programme.

AIMS AND CONTENT

LEARNING OUTCOMES

Introductory Statistics. In the course the main topics of descriptive statistics, probability and inferential statistics are discussed.

AIMS AND LEARNING OUTCOMES

Knowledge and understanding: Students will know the main tools used to summarize the information and for the generalization of the information observed through sample surveys.

Ability to apply knowledge and understanding: Students will be able to reorganize data in univariate and bivariate frequency tables providing adequate graphical representation; carry out basic descriptive analyses for one-dimensional phenomena; analyze the relationships between two or more phenomena with particular emphasis on dependence and linear regression analysis. They will also be able to apply some statistical inference tools to solve simple problems.

Making judgements: Students must be able to use the acquired knowledge both on a theoretical and operational level with autonomous assessment skills, in various applicative contexts.

Communication skills: Students will acquire the technical language typical of the discipline to communicate clearly and without ambiguity with both statisticians and non-statisticians.

Learning skills: Students will develop adequate learning skills that allow them to continue to study the subject independently.

 

PREREQUISITES

The course requires knowledge of the basic contents of a course of General Mathematics for Business and Economics.

Teaching methods

Traditional lessons and exercises and through AulaWeb. Since the training objectives concern both theoretical and applicative skills, there will be both lessons focused on the methodological aspects of statistics and lessons based on exercises in which numerical problems are faced and examples of simple analyzes on real data are discussed.

Due to the Covid19 pandemic, students will be informed via email and AulaWeb messages on the actual method of the lessons (in person or remotely).

LESSONS

Teaching methods

Traditional lessons and exercises and through AulaWeb. Since the training objectives concern both theoretical and applicative skills, there will be both lessons focused on the methodological aspects of statistics and lessons based on exercises in which numerical problems are faced and examples of simple analyzes on real data are discussed.

Due to the Covid19 pandemic, students will be informed via email and AulaWeb messages on the actual method of the lessons (in person or remotely).

LESSONS START

Classes will start in the first week of the second semester according to the calendar of the Department of Economics.

EXAMS

Exam description

The examination consists of a written test. As a result of the COVID 19 pandemic, the examination procedures may change in relation to the University regulations. The examination regulations are published on the course's Aulaweb page.

 

Assessment methods

The written examination consists of:

1) multiple-choice questions of a theoretical nature.

2) theoretical questions with open answers

3) exercises

The questions and exercises are chosen to cover, as far as possible, all the topics of the program. The theoretical questions are used to assess the student's level of understanding, while the exercises are used to measure the ability to apply the acquired knowledge.

 

FURTHER INFORMATION

Additional information for non-attending students

For non-attending students, no program changes or assessment procedures are applied. Non-attending students are however invited to contact the teacher.
