Examination Methods

The assessment of learning outcomes consists in a written examination.


Examination purposes
The written examination assesses the level of knowledge of the course topics, the ability to apply statistical methods for business and the interpretation of results.


Structure of the examination
The examination consists of single and multiple choice questions, questions which requires a numerical response, and open-ended questions. All kinds of questions may be focussed on theoretical and methodological issues, may consist in exercises, or may require the student to discuss and analyse some practical problem using notions and tools learned throughout the course.

The teacher may require students to take an oral examination which completes the evaluation of the acquired knowledge. The final grade may be equal, higher or lower than the grade got on the written part of the exam.


Assessment criteria
The examination score is on a 30-point scale (passing mark: 18).
