Intended Learning Outcomes (ILO)
KNOWLEDGE AND UNDERSTANDING
 Understand basic concepts of probability required for the use and interpretation of statistical methods.

Describe a dataset through adequate graphs, tables and statistics.

Identify if the structure of the data allows the application of basic statistical inferential methods.

Do inference on the mean of a population (point estimation/ prediction, interval estimation, hypothesis testing).

Understand the fundamental logic of estimation and hypothesis testing.
APPLYING KNOWLEDGE AND UNDERSTANDING

Understand the challenges derived from the presence of uncertainty in reallife situation.

Choose and apply adequate (basic) statistical tools to aid in the decisionmaking process by learning from available data.

Interpret charts, graphs and statistics and identify possible misrepresentations of data.

Question statements based on data, by analysing the statistical elements and the validity of the assumptions made.
Teaching methods

 Exercises (exercises, database, software etc.)
DETAILS
Exercises (Exercises, database, software etc.):
Special sessions with exercises, examples and illustrations of concepts and methods, also with the help of statistical software R, will be provided.

ATTENDING AND NOT ATTENDING STUDENTS
Students may choose between the following two options:
 Two partial written exams (a midterm and a final) that contribute to the final grade with a 50% weight each.
 A single general written exam (after the end of the course) that counts for 100% of the final mark.
The tests consist of exercises. They aim at ascertaining students' mastery of concepts and results discussed during lectures as well as an adequate knowledge of R.
In each test the maximum grade is 31, and questions related to R count for 4 points (of the 31).
The assessment method is the same for both attending and nonattending students.
Students who take the midterm exam may still take the general exam instead of taking the final exam.
Importantly, access to the final (or second partial) exam follows the rules indicated in Section 7.6 of the Guide to the University.
