Probabilidades e Estatística

Teaching Methodologies

The expository method is mainly used in theoretical classes, with the introduction of concepts and techniques, accompanied by examples associated with real data with application in the area of biomedical engineering. In theoretical-practical classes, students individually solve the exercises proposed by the teacher.
The Assessment may be carried out on a Distributed basis or by Final Exam. The distributed assessment consists of two tests, each lasting 1h30m and quoted at 10 points. The student can pass if the minimum grade in each of the tests is 4 values and the sum of the two grades is equal to or greater than 10 values. Assessment by Final Exam consists of an exam rated at 20 points, obtaining approval with a grade equal to or greater than 10 points.

Learning Results

Objectives: it is intended to transmit to students the fundamentals of Statistics necessary for the analysis and interpretation of data, especially in the area of health sciences, to present the main probability models with application in the fields of engineering.
Skills: learn the main methods of data interpretation and analysis and the probabilistic models that form the basis of statistical inference. Learn the basic tools of statistical inference, confidence intervals and hypothesis testing. Master the simple linear regression technique.
