StatsGuru for R

StatsGuru for R is aimed at students learning about statistics and contains information on a comprehensive list of typical statistical tests that college or university level students may be expected to know.
The main feature is the decision tree, this allows users to answer a series of questions about their data and discover the most appropriate test. Each test covered features a basic overview plus guides, using a practical example, on how to input data and run the analysis, what to look for in the output (interpretation) and an example write-up. There is also a searchable glossary, covering the most common statistical terms used in the social sciences.
StatsGuru for Matlab, R and SPSS are produced by Jonathan Catling (PhD) and Graham Fowler (MRes) at the University of Birmingham, UK.
