Objetivos
The curricular unit contents are structured, regarding its suitability for the intended learning outcomes.
Therefore, each subject approaches fundamentals concepts and practical applications by solving problems using the basic tools of Statistics to enable students to analyze certain phenomena of random nature, framed in the context of 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.
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):
-If MF is greater than or equal to 10 and less than 18, the student is approved with a final mark equal to MF, provided that the classification in any of the tests was greater than or equal to 7.0 values.
- If the MF is equal to 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 MF 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 than 7.0 values.
Exam Evaluation
-If the grade of the exam is greater than 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 to 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.
