Statistics and Data Analysis 2 2017/2018

  • 5 ECTS
  • Taught in Portuguese
  • Continuous Assessment

Objectives

By the end of this curricular unit, the student should be able to:
• Understand the rational underlying the procedures of statistics and data analyses using the IBM SPSS software
• Know the different techniques of statistical analyses, understand their utility, and know when to apply then, using IBM SPSS;
• Evaluate the association between variables and test prediction models
• Analyze differences between groups and between different evaluation moments;
• Recognize the assumptions and basic results of exploratory factor analyses;
• Interpret in a critical way the results of data analyses and report those results in research reports, according the APA guidelines and norms;
• Develop autonomy in using the statistical procedures requires to carry out research project, as well as in reading and interpreting results that are presented in scientific publications.

Recommended Prerequisites

Prior knowledge based on the contents learned in Statistics and Data Analysis I is recommended.

Teaching Metodology

The theoretical and practical classes will aim for a compromise between expository methodologies and active and participatory methodologies. Expository methods will be based on the use of multimedia supports, using for this purpose the IBM SPSS software, PowerPoint slides, reading and discussing documents, and managing databases. The active methods will be based on practical activities, including the exploration of databases and statistical analyzes exercises using the SPSS. These practical activities will seek the active resolution of psychology research problems as well the reporting of research results in the form of reports, individually and with mentoring from teachers.

The evaluation methodology will be continuous, with three evaluation components to be carried out throughout the semester: one written test to evaluate knowledge(worth 40% of the final grade) and two practical group tasks (which worth 30% of the final grade).

Demonstration of the syllabus coherence with the curricular unit's objectives

In order to provide students with the acquisition of critical thinking skills about the usability and selection of statistical analysis procedures for the support of research, the syllabus include a variety of inferential data analysis, from tests of association between variables to group comparisons. In order that students associate these statistical procedures with research in psychology, the program contents include the analysis and reflection of data analysis results and testing of empirical hypotheses. Finally, in order to develop interpretation and reporting research results skills, the syllabus include the analysis of statistical analysis outputs and writing scientific reports according to APA norms.

Demonstration of the teaching methodologies coherence with the curricular unit's objectives

The use of expository methods enables the transmission and analysis of new contents relating to data analysis techniques using the SPSS software. These methods support the acquisition of basic knowledge in the field by the students. The use of methods involving the active participation of the students is accomplished through the analysis and interpretation of research results published in scientific papers, as well as problem solving applied to psychology with the selection and implementation of data analysis techniques. Group assignments will contribute to the acquisition of critical thinking skills about the data analysis procedures, and the interpretation and reporting of research results. The combination of these different methods will, thus, allow the accomplishment of the goals set forward for this curricular unit.
