Summary module description:

This module focusses on exploratory multivariate data analysis techniques, where the aim is to identify similarities and differences between observations based on several variables.  Multivariate data analysis techniques have a long history of being applied to analyse data from a wide range of disciplines such as psychology, and marketing and research.  This module will introduce several techniques covering the underlying theory, as well as carrying out the analysis using software and interpreting the results.

Aims:

In many experiments or surveys, several different variables are recorded for each of many individuals.  The problems associated with this sort of data can be tackled using multivariate data analysis techniques.  The methods to be discussed will be descriptive in nature and include the following topics: principal component analysis; canonical variates analysis; cluster analysis; and factor analysis.  The theory of the methods will be shown, together with how to apply them in practice.

Assessable learning outcomes:

By the end of the module it is expected that the student will have:

• knowledge of the role of multivariate data analysis in statistics;

• the ability to identify, justify and explain the most appropriate statistical techniques for a multivariate dataset;

• the ability to carry out commonly used multivariate data analysis techniques, and interpret the results;

• the ability to independently research multivariate data analysis techniques and learn how to apply them;

• the ability to use statistical software packages for the analysis of multivariate data.

This module will be assessed to a greater depth than the excluded module ST3MVA.

Outline content:

Penalties for late submission:
The Module Convener will apply the following penalties for work submitted late:

• where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that piece of work will be deducted from the mark for each working day[1] (or part thereof) following the deadline up to a total of five working days;
• where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

• The University policy statement on penalties for late submission can be found at: http://www.reading.ac.uk/web/FILES/qualitysupport/penaltiesforlatesubmission.pdf
You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

Assessment requirements for a pass:

A mark of 50% overall.

Reassessment arrangements:

One examination paper of 2 hours duration in August/September (70%) and one assignment (30%).
