## 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.

## Objectives

Following completion of this course, you should be able to:

• Understand important statistical concepts and terminology
• Understand the basic statistical framework used in the design and analysis of health related studies
• Use a computer software package for elementary data analysis
• Complete a detailed statistical analysis of a simple study
• Critically appraise scientific research from a statistical perspective
• Understand the principles behind more complex statistical analyses
