There are 48 course hours, 38 of which are ordinary lectures where the syllabus is covered. The remaining 10 hours will be dedicated to SAS JMP or Excel demonstrations in class.

For each week there will be given a work programme with literature references and exercises. Training / use of Excel will be integrated into teaching. In the lectures the theory will be exemplified by a set of SAS JMP data samples with exercises. The final exam is loosely based on these SAS JMP examples.

The course uses an appropriate statistical software.
