# Statistics and Information Systems

## Objectives

To enable students to apply methods from statistics and computer science to real-world data sets in order to answer business and other questions, in particular with application to questions in long and short term insurance, social security, retirement benefits, healthcare and investment.

Practical problems corresponding to real situations will be privileged.

### Teaching method

The main objective of the Curricular Unit is to provide students with computational skills suitable for the statistical treatment of large data sets.

The teaching methodologies will be essentially of a practical nature, in computer labs, after introducing the elementary concepts of adopted software.

### Evaluation method

Continuous evaluation

• Test (T)
• Group Assignment (TG)

Final Grade = 0.6T + 0.4TG

Failure to complete any component implies a zero score, in this component, for calculating the Final Grade.
