Module prerequisites:PSYC2204 The Design and Analysis of Psychological Experiments. Students without Maths at A-level or equivalent should consider carefully the difficulty level of this course, which uses matrix algebra quite extensively. Non-Psychology students wishing to take this course as an elective need to contact the Psychology Third Year Tutor. Affiliate students need to contact the UG Teaching Administrator for Psychology. Without tutor agreement the choice will not be approved on Portico.

Module outline:Most psychological datasets are inherently multivariate, and proper analysis requires that the subtleties of the interrelationships between multiple measures are taken into account. The advent of cheap computing power and sophisticated computer packages in the past couple of decades has transformed psychological statistics, and this module introduces a range of techniques which once were only for specialists and now are increasingly expected of all psychologists. The first half of the module concentrates on multiple regression, and the problems that can arise in what is effectively a paradigmatic case for all multivariate analysis, and the second half extends the analysis into properly multivariate techniques such as factor analysis, MANOVA, canonical correlation and path analysis. The examples classes are an integral part of the course, not only providing practical experience, but also supporting the lecture material. 
Module aims:To understand a range of modern techniques used in the statistical analysis of multivariate data in psychology. 
Module objectives:By the end of the module you should: • Understand the principles of basic matrix algebra, including the concepts of an eigenvalue and a determinant, be able to manipulate simple matrix equations, recognise the applications of matrix algebra to multivariate statistics, and be able to carry out matrix calculations using Matlab. • Understand the basics of multiple regression, including its matrix formulation, the problems of multicollinearity, suppressor variables and missing values, the use of dummy variables, polynomial terms, interaction terms, the relationship to ANOVA, and the differences between forward and backwards stepwise models, and hierarchical models. • Be able to use Matlab to carry out multiple regression analyses, including the use of macros, and to be able to carry out a Monte Carlo analysis using Matlab to generate random variables of known distributions. • Understand the basics of exploratory factor analysis, including its matrix representation, the use of principle component analysis for data reduction, the advantages and disadvantages of the eigenvalue>l and scree-slope criteria for the numbers of factors, and the nature of rotation, including Varimax and oblique rotations. • Understand the difference between confirmatory and exploratory factor analysis and the advantages of each, the application of path analysis to understanding simple problems of test-retest correlations, etc., and the relationship of path analysis to matrix representations. • Understand how factor scores can be used for reducing a complex set of dependent variables to orthogonal measures which can be used as dependent variables in regression or ANOVA, and how multiple regression can be generalised to multiple dependent variables as canonical correlation and similarly ANOVA can be generalised as MANOVA. • Understand the basic form of structural equation modelling in the specific form of the LISREL model, and be able to describe the purposes of the various matrices in the formulation. • Be able to use SPSS for Windows to carry out multiple regression, factor analysis, canonical correlation and MANOVA. Be able to interpret the various forms of output and to recognise the common options available for the various programs. • Be able to use LISREL for Windows to carry out a simple confirmatory factor analysis, and recognise the various parts of the output from the program.
