# Statistics

## Objectives

he aim of the course is to provide students a basic knowledge of Probabilities and Statistics which are an indispensable tool for decision making under uncertainty.  In addition, the course helps students gain an appreciation for the diverse applications of statistics and its relevance to their lives and fields of study.

At the end of the unit students will have acquired skills that enable them:

-Know and understand the basic elements of the theory and the calculus of probabilities

-Describe the main probabilistic distributions of discrete and continuous variables and applies them in the description of random phenomena

-Infer about population parameters based on sample distributions

-Build-statistical models, which establish a functional relationship between variables

### Teaching method

Lectures and problem-solving sessions, with wide participation of students.

### Evaluation method

The classes take place with an oral presentation of the subjects, followed by practical examples. Learning is complemented by solving exercises.

Only be admitted for evaluation students who have a maximum of 9 faults or who attended last year.

CONTINUOUS EVALUATION
The students obtain approval if the weighted average of the two tests is greater than or equal to 9.5.

Final mark = 50%T1 + 50%T2

EVALUATION BY EXAM
The evaluation by exam is valid both for grade improvement as for discipline approval. The student with a final score greater than or equal to 18.5 should carry out an oral defense of note. Otherwise, will get a final score of 18.0.

More detailed rules are available in the Portuguese version.
