Suggested background knowledge

To feel comfortable with some topics in this course, students should be familiar with differential and integral calculus.


Mission & Content Summary
MISSION

The main aim of the course is to introduce students to probability theory, the logic of uncertainty, and statistics, which represent fundamental methodological tools for modern applications in Science and beyond. Students are expected to get familiar with key principles of probability theory and statistical thinking, both descriptive and inferential. Several examples and illustrations of concepts and methods will be provided, also with the help of the statistical software R.

CONTENT SUMMARY
  • Combinatorics, probability measures and related elementary properties.
  • Conditional probability and independence.
  • Discrete and continuous random variables. Notable examples. Expected values.
  • Joint distribution, independence, correlation, conditional distributions.
  • Descriptive statistics, population and sampling, frequency tables, graphs, measures of location and spread.
  • Distributions of sampling statistics and related asymptotic distributions.
  • Point and interval parameter estimation.
  • Hypothesis testing.

Intended Learning Outcomes (ILO)
KNOWLEDGE AND UNDERSTANDING
At the end of the course student will be able to...
  • 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
At the end of the course student will be able to...
  • Understand the challenges derived from the presence of uncertainty in real-life situation.

  • Choose and apply adequate (basic) statistical tools to aid in the decision-making 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
  • Face-to-face lectures
  • 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.


Assessment methods
  Continuous assessment Partial exams General exam
  • Written individual exam (traditional/online)
  •   x x
    ATTENDING AND NOT ATTENDING STUDENTS

    Students may choose between the following two options:

    - Two partial written exams (a mid-term 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 non-attending students.

     

    Students who take the mid-term 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.
