Overview

This paper will emphasise computer data analysis with the goal of providing students with the tools for basic analysis of their research projects, including statistical aspects of study design, data description, handling data on a computer, using a statistical software package, and carrying out and interpreting simple statistical analyses. Familiarity with basic mathematical concepts is essential.
