### Course Overview

Statistics is about "making decisions in the face of uncertainty". Where should the next hospital be built in Sydney? It takes years to build a hospital, and we want to build it where it will be the most useful when it is built.... What is the best medication to treat a particular infection? ... Are two medications equally effective?

In statistics we attempt to gain or improve our understanding of the world using the information gleaned from sets of data. People in government study data in order to make informed planning decisions. Doctors, biologists, pharmacists, psychologists, geologists and many others need to understand the origins, trustworthiness and analysis of the data that appears in journal articles.

Statistics is the science of collecting, organising, analysing, and interpreting data. We introduce some of the ways of obtaining data, and what sort of questions someone might hope to answer using statistics. We look at various ways of summarising or graphing the data to get a good overview. We develop the ideas of statistical inference, that is:

- Testing hypotheses - for example "do we have enough evidence to conclude that a new product works better? or faster"; How much evidence would we need to make such a decision? "Does bread lose vitamin C when it is stored?"....
- Estimating important parameters with required levels of accuracy - how much faster does the new product work? How much vitamin C does bread lose when stored for one day? One week?...
