This course provides a refresher on the foundations of statistical analysis. Practicals are conducted using the 'Shiny' package; which provides an accessible interface to the R statistical language.
Note that this is not a course for learning about the R statistical language itself. If you wish to learn more about R, please see other courses at the University of Cambridge
