Communication skills Achievement of this objective will be assessed by means of written examinations, individual and group assignments and the final dissertation.

Art der Prüfung
Assessment (for both attending and non-attending students): - Written Midterm Exam (optional): Covers approximately half of the course topics. Contributes 40–50% of the final grade, depending on the content. - Written Final Exam: Covers the remaining topics if the midterm was taken (50–60% of the final grade), or the entire course if the midterm was not taken (100% of the final grade). Note: the grade of the midterm will remain valid for one year.

Bewertungskriterien
Both the written midterm and final exams consist of theoretical questions and exercises. They will be evaluated on the basis of clarity of exposition, knowledge and understanding of statistical methods, ability to apply appropriate statistical procedures, correctness of the results. The capability to read and interpret R outputs will be crucial for the solution of some exercises.
