Evaluation Methodology
By frequency: two written tests, rated from 0 to 20, each corresponding to 50% of the total grade. The student is exempt from the exam if the grade in each test is equal to or greater than 6 points and if the average of the two tests is equal to or greater than 10 points.
By examination: written test on all subjects taught.
The student is approved if the classification obtained is equal to or greater than 10 points.

Teaching Method
Theoretical classes in which will be describe and exemplify the concepts inherent to the contents taught, and theoretical-practical classes in which exercises are proposed to apply the concepts taught.
Software used in class
The Excel spreadsheet and the IBM SPSS statistical package are occasionally used to solve some exercises.
