Data Analysis

Recommended Prerequisites

Not applicable.

Teaching Methods

The methodology includes lectures, using audiovisual means and practices in computer room. It seeks to promote an active and participatory learning, focusing on the interaction, in order to better understand the logic that precedes the use of statistical tests.

Knowledge evaluation is performed by conducting a written work (80%) and correspondent presentation and discussion in the class (20%). The classification is assigned from zero to twenty values, being guaranteed approval with the minimum rating of ten values. 

Learning Outcomes

This course aims at sensitizing the students to the importance of data analysis methodologies in what concerns health science research. Moreover, it presents the various phases of the empirical research prior to data analysis, from the statement of the problem to the data collection techniques and the definition of research strategy, variables choice and operationalization, as well as sampling methods. Finally, a better knowledge of the statistical proceedings is created, namely the simple descriptive statistics, and the hypothesis testing to study comparisons and association among variables. At the end of this course, students will be able to, independently, produce the statistical analysis they need in preparing their dissertation, and later on in their professional lives.
