Teaching Methods
The teaching is provided in both theoretical and theoretical-practical sessions. The theoretical lectures are expository and include the presentation of examples. In order to apply the acquired knowledge, the theoretical-practical sessions are focused on solving a complete set of practical exercises.
Small projects involving the development of simple statistical models and computational tools may be suggested to develop critical skills and interpretation of results.
Weekly, tutorial time is offered to help students to overcome their learning difficulties.
Learning Outcomes
The aim of this course is to introduce basic mathematical knowledge to prepare the student to model the behavior of random phenomena arising in the context of health sciences. It contributes to prepare students to describe, analyze and interpret real situations using non-deterministic mathematical models. The correct use of statistical methods in specific cases and the strict interpretation of the results require a theoretical base in Statistics, for which this course contributes.
It is also intended to prepare students for applying statistical methods and concepts to real situations involving the estimation of parameters of a model, testing its fitness and getting explanation to interpret, predict and decide on the phenomena under study.
This unit allows developing the following skills: analysis and synthesis, problem solving, critical thinking, work in interdisciplinary teams, autonomous learning, adaptability to new situations and application of theoretical knowledge.
