The purpose of this subject is to introduce students to concepts of research methodology and design as they apply to experimental psychology research. Students will learn about the scientific method and issues such as probability, causality and sampling. They will also acquire skills in designing experimental studies by learning to formulate research hypotheses and the operationalisation of concepts into variables. Problems that can arise with research, such as threats to validity and reliability, will also be presented. In addition, students will acquire skills in inferential statistics, including hand and computer calculation of parametric and nonparametric statistical tests. A major component of the subject will be the acquisition of skills in using the statistical package SPSS, as well as presenting research findings in APA format. It is intended that by the completion of this subject students can integrate the methodological understanding and the analytical and computer skills acquired in this subject.
