Course syllabus and organization
Single session
Responsible
More specific information on the delivery modes of training activities for academic year 2021/22 will be provided over the coming months, based on the evolution of the public health situation.
Prerequisites for admission
Required preliminary knowledge: Basic algebra and elements of geometry.
Assessment methods and Criteria
Statistics: Written examination with a combination of multiple-choice questions (1 right, 4 wrong answers) and small problems or toy examples with a series of questions to reply. Every question has its mark indicated in the written examination. Students who gain
a final mark higher than 30 will receive a mark of 30 cum laude. A calculator and the tables of the probability distributions found in Ariel are necessary to solve the written examination. Students are allowed to fill in a form with all the formulas to keep during the examination. Results will be provided to the students via Ariel.
Informatics: Resolution of a computer exercise using the Excel program (Microsoft). Each correct question is worth about 3 points. The sum of the points corresponds to the final outcome of the test. The test is passed if the sum of the points is greater than or equal to 18

Teaching methods
Teaching through slides and blackboard use with a problem-solving approach; practical sessions of exercises; slides and exercises available from Ariel for additional homeworks.
The lecturers and practical sessions have done in a classroom using computers using the Excel program (Microsoft). Each lesson has the structure of a practical training session: in each lesson one or more problems related to the various topics of the course are solved on the computer. Each practical training session is preceded by the projection of PowerPoint slides related to the theoretical topic of the session.
