Base Knowledge
Univariate and bivariate descriptive statistics
Teaching Methodologies
The development of each topic in the course will have a similar structure, in particular: a introduction and characterization of the technique and a presentation and discussion of the options and the output of SPSS, using an example.
Assessment consist of two assignments, one indivual and the other in group. In each assignment a database should be collected, one of the studied techniques must be applied and the results should be properly interpreted. The two techniques chosen must be different. Each assignment should be presented in the form of a written report and shall be subject to oral defense.
Learning Results
The main goal of this course is to provide students with a set of techniques for data analysis when they involve more than two variables. In particular, it is intended that students deepen and broaden the knowledge they need to analyze data, understand the need of the covered techniques, apply them using an appropriate software (SPSS) and correctly interpret the results.
