Statistics and Data Analysis 1 2017/2018

  • 5 ECTS
  • Taught in Portuguese
  • Continuous Assessment


By the end of this curricular unit, the student should be able to:
-Distinguish the continuous or discrete nature of the variables;
-Acknowledge and interpret case count and distribution results;
-Identify, apply and interpret results from central tendency and dispersion measures;
-Identify, apply and interpret results from statistical tests of association, simple linear regression and simple logistic regression according to the variables’ scale of measurement;
-Acknowledge and use the IBM SPSS interface to insert data and conduct descriptive statistics, normality distribution, association, simple linear regression and simple logistic regression analyses.

Recommended Prerequisites

It doesn't apply.

Teaching Metodology

Classes will include theoretical and practical components to foster the continuous consolidation of the lectured statistical concepts and operations with practical applications in the IBM SPSS software. Whenever possible, theoretical and practical classes will include the critical analyses of published articles and supervised problem solving. Specific references will be recommended at each class for students to deepen their study of the lectured contents. A continuous evaluation methodology will be used, including two short-tests and a group assignment.

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

The coverage of basic statistics and data analysis concepts crosses all the curricular unit’s contents and sustains the attainment of the remaining learning goals. The descriptive statistics topics afford students the possibility to understand the continuous or discrete nature of variables, the normality of data distribution, and how these contents are applied in SPSS. The inferential statistics contents foster students’ understanding of statistical assumptions and adequacy of association tests and simple linear regression to different variables. All the contents will be practically applied in SPSS, thus stimulating students’ knowledge and use of its interface to solve problems.

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

Contents will be lectured in a permanent articulation between theoretical exposition and practical application/interpretation to sustain students’ future work in Psychology research. For coherency with the teaching methodology, a continuous evaluation method is used to assess students’ theoretical comprehension and practical application of the covered contents, considering the interpretation of information and problem solving. The group assignment will focus on a critical analysis of a scientific manuscript published in Portuguese, taking the interpretation and discussion of the used statistical data analyses into account.
