Course Outline and Class Schedule [PDF] or [HTML]

Psychology 6140 is designed to provide an integrated, in depth, but applied approach to multivariate data analysis and linear statistical models in behavioural science research. There is a strong emphasis on using graphical methods to understand your data. The statistical topics covered will include:

Regression analysis
Univariate and multivariate ANOVA and ANCOVA
Discriminant analysis
Logistic regression
Canonical correlation analysis
Principal components, factor analysis, LISREL models (CFA, SEMs)
Cluster analysis and Multidimensional Scaling (time & interest permitting)

See the more detailed Course Outline for further information, and the class schedule for lecture notes and tutorials. See the Hebb Lab website for information on access to the Hebb Psychology Computer Lab.

Resources

Statistical software

York group licenses for SAS and SPSS Worthwhile to have at least one of these on your own PC.
You may also be able to use the Web Acadlabs service to access SAS, SPSS from home. See
Accessing software remotely using Web Acadlabs by Manolo Romero.
R Project for Statistical Computing. R is a free software environment for statistical computing and graphics (Windows, MacOS, Linux).
You can download it from any CRAN mirror site.
See John Fox's notes, Installing R for Windows.
