Postgraduate Course: Multivariate Statistics and Methodology using R (PSYL11054)
|School||School of Philosophy, Psychology and Language Sciences
||College||College of Humanities and Social Science
|Credit level (Normal year taken)||SCQF Level 11 (Postgraduate)
||Availability||Available to all students
|Summary||The semester long course provides an advanced level overview of a variety of statistical analysis techniques and methodology issues relevant to psychological research. It is taught using a combination of lab and lecture sessions and focusses on techniques used by students following Masters programmes in Psychology and Linguistics and researchers practicing in these areas.
R is a language and environment for statistical computing and graphics that is highly flexible and increasingly popular for statistical analysis. It provides a wide variety of statistical and graphical techniques, including facilities to produce well-designed publication-quality plots.
Design and analysis are taught under a unifying framework which shows a) how research problems and design should inform which specific statistical method to use and b) that all statistical methods are special cases of a more general model. This course focuses on situations in which 2 or more outcome variables are being studied simultaneously.
- Linear Mixed Modelling (5 lectures)
- Factor Analysis (1 lecture)
- Confirmatory Factor Analysis (1 lecture)
- Path Analysis & Structural Equation Modelling (3 lectures)

|Additional Information (Assessment)
||End of course assignment: a data analysis exercise (take home exam) 100%.
Page limit: 6 pages for the write-up (2 pages of text and 4 pages of tables/figures). You may include references which do not count towards the page allowance. The report should be written in a standard font, size 12, with standard 1 inch (2.54cm) margins on all sides.
R-code: You must submit the R-code used to produce the results presented in the report. This code must run without error. Any errors will result in a 10% deduction from the final grade. There is no limit for the R-code which will be submitted alongside the report.
||Lab practicals that provide direct feedback on exercises and queries. Q&A sessions held once a week with course Teaching Assistants. Model answers for all lab and homework exercises.
|No Exam Information
On completion of this course, the student will be able to:
- understand a variety of issues regarding the choice of statistical analysis techniques for standard and unusual data sets
- understand how to use the R language as a tool for data manipulation, analysis and graphics
- become adept in expressing statistical models typically used in psychological research and interpreting their results
