    Compentences and Skills that will be Acquired and Learning Results:

    In today's world there is an enomous amount of available information. There are diverse sources and many of them are accessible through the Internet. To analyze this information and draw valid conclusions we need to use some specific techniques. Statistics is the most widely used and the most successful technique. In this course we will learn how to obtain information from the data with techniques that you will use both in your studies and in your professional career, because these techniques are commonly used by most companies and organizations.

    Today a statistical analysis is inconceivable without computer resources. Therefore the teaching of Statistics will rely heavily on computer practices and a part of the final exam will be held in a computer classroom.

    After completing this course, you should be able to extract information from the data and to express those conclusions in a written report. Also, you can establish relationships between variables using the regression model and to interpret the model properly.

    5.2 Null hypothesis and alternative hypothesis.
    5.3 Hypothesis testing for the mean, proportion and variance of one population.
    5.4 Hypothesis testing for two populations: Difference of means and proportions.

    Learning Activities and Methodology:

    - Lecture: 2,5 ECTS
    - Problem solving sessions (in small groups): 1,5 ECTS
    - Computes sessions (consistent of individual work out of the classroom with programmed tutorial sessions) 1,5 ECTS
    - Evaluation sessions (continuos evaluation, some of them at computes laboratories): 0,5 ECTS

    Assessment System:

    The final grade will be computed giving a 50% weight to the grade in the final exam and a 50% weight to the continuous evaluation grade. A minimum of 5 points on the final exam will be required.

    The continuous evaluation consists of a midterm theoretical exam and a practice exam. The midterm exam will render 10% of the final grade, while the practice exam will render 40%. You have to present the practice workbook and take the practice exam. Without any of these two things, the grade in the practice part of the course will be 0.

    Summarizing:

    10% Midterm theoretical exam
    40% Practice workbook + Practice exam (May)
    50% Final exam

    The assessment system applied to the students that have not followed the continuous will be the most favourable to the student under the University rules.
