## Synopsis

This unit introduces students to biostatistics as applied to public health and management studies. Biostatistics is the science of describing, summarising, and analysing health-related data. It is essential to understand biostatistics in order to design, conduct, and interpret health-related research. The basic principles and methods used in biostatistics are covered in this unit, including the technical qualifications necessary for analysing and interpreting data on a descriptive and bivariate level.

Topics include classifying health data; summarising data using simple statistical methods and graphical presentation; sampling distributions; quantifying uncertainty in results from a sample; working with statistical distributions; comparing two or more groups/methods using confidence intervals and hypothesis tests (p - values); assessing the association between an outcome and an exposure using the chi-squared test; using risk comparisons (RR and OR); predicting an event or identifying risk factors for an event of interest where the event is measured on a continuous scale or a binary scale (yes/no).

## Outcomes

Upon successful completion of this unit, students should be able to:

1. Classify data into appropriate measurement types.
2. Present data using relevant tables, graphical displays, and summary statistics, quantify uncertainty in study results.
3. Formulate research hypotheses into a statistical context in public health studies.
4. Estimate quantities of interest and evaluate hypothesis with appropriate statistical methods.
5. Accurately interpret statistical methods and results reported in health publications.
6. Analyse data using a specific software package.
