Description
Graphical analyses complement statistical analyses.  Their advantages lie in checking data quality, in generating hypotheses (in contrast to testing them) and in explaining model results.  Graphical methods are becoming increasingly important for the analysis of large heterogenous datasets, for which classical model assumptions seldom hold.  In this lecture we will discuss graphical methods using examples from real applications, including some from the web.  R will be used primarily (especially ggplot2) with Mondrian for interactive graphics.

Assessment

The assessment will be by project work presented and examined orally.  Examples can be found here and will be discussed in the last tutorial before Christmas.

There will be an independent module at the start of next summer term.
