Objetivos

The curricular unit contents are structured, regarding its suitability for the intended learning outcomes.
Therefore, each subject approaches fundamental theoretical concepts and practical applications by solving problems using the basic tools of Probability and Statistics to enable students to analyze certain phenomena of random nature, framed in the context technology.

Obtenção de frequência

The approval in this curricular unit can be obtained through two assessment processes: Continuous Evaluation or Exam Evaluation.

Continuous Evaluation 
2 tests and 3 practical work developed in group.

Exam Evaluation
Evaluation by final examination.

Fórmula de cálculo da classificação final

Continuous Evaluation 
Assigning by MT the average of the tests (from zero to 20)  and by MTrab the average of the practical work developed in group (from zero to 20), the final classification (CF) is:

• If CF is greater than or equal to 10 and less than 18, the student is approved with a final grade equal to CF, provided that the classification in any of the tests was greater or equal to 8.0 values.


• If the CF is equal or greater than 18, the student must do an oral exam. The final grade is the average between the tests and the grade of the oral exam. If the student does not attend the oral exam, the final classification will be 17 points.


• If CF is less than 10, students will be able to recover the lowest test by performing a recovery test (in the same day of the first exam), provided that one of the tests is greater or equal to 8.0 values.

Exam Evaluation

• If the grade of the exam is greater or equal to 10 and less than 18, the student is approved with a final mark equal to the grade of the exam.


• If the grade of the exam is equal or greater than 18, the student must do an oral exam. The final grade is the average between the two grades. If the student does not attend the oral exam, the final classification will be 17 points.
