Biostatistics in Population Health (POPH4101)

This course will examine principles of biostatistics, in the context of real-world public health issues. The aim of the course is to help those without a specialised background to read and interpret biostatistical content in the medical and public health literature.

Topics, chosen by frequency of occurrence in the literature, will include:

• Introduction to sampling distributions, hypothesis tests and estimation
• Analysis of normal data, including t-tests and linear regression
• Analysis of binary data, including 2x2 tables, Mantel-Haenszel methods and logistic regression
• Analysis of count data, including comparing rates between two groups
• Poisson regression

Throughout the course, the emphasis will be on understanding the reasons why the techniques are appropriate, underlying assumptions, use of the statistical analysis package Stata and interpretation of results, rather than the mechanics of calculation. Each topic will draw upon one or two papers from the literature. Both online materials and drop-in help sessions in a computer lab will be used to facilitate learning and provide opportunities to explore specific topics in more detail.

## Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

1. Define and explain mathematical and biostatistical concepts covered in the course.
2. Produce appropriate visual displays and summary statistics for datasets, and describe the shape and properties of the data from those outputs.
3. Choose and implement appropriate statistical models and tests and interpret their outputs to make inferences from data; continuous outcomes, binary data, categorical data, survival data.
4. Produce appropriate diagnostic plots for statistical models and use these to critically assess the assumptions of the model against the data.
5. Construct functioning scripted statistical analysis (in STATA or R) to load, wrangle, and analyse a dataset.
6. Critically assess the statistical methods and evidence presented in published research studies.

## Research-Led Teaching

This course will use current research articles/projects to introduce students to interesting topics and problems in the field of biostatistics.

This course will uses STATA for data analysis. Students will have access to a limited version of this program provided by ANU. Students who are interested in ongoing use of this program may wish to consider purchasing their own personal licence for STATA.

## Required Resources

·       Betty R Kirkwood & Jonathan AC Sterne. Essential Medical Statistics (2e). Oxford: Blackwell Science Ltd, 2003.

‘Essential Medical Statistics’ is considered a classic among medical statisticians. An introductory textbook, it presents statistics with a clarity and logic that demystifies the subject, while providing a comprehensive coverage of advanced as well as basic methods. It is available for purchase from the Co-op Bookshop (Bldg #17 Union Court; Tel (02) 6249 6244). The Hancock Library (Bldg #43) also holds several copies for loan (RA407.K57 2003).

·       Stata B/E.

This course includes a hands-on introduction to the statistical analysis software Stata, the product of choice of most public health data analysts. You can use the software on computers in the Crawford Building (Bldg #132). It can also be purchased online through a company based in the ACT, https://www.surveydesign.com.au/stata/buy.html. You can buy a licence for as short as 6 months, or a perpetual licence.

If you find that there are sections that you are struggling with, try some supplementary reading of either of these books:

·        Bland, M. An Introduction to Medical Statistics (3e). Oxford: Oxford University Press, 2000.

·        Daniel WW. Biostatistics: A Foundation for Analysis in the Health Sciences (9e). New York: John Wiley & Sons, 2009.

If you are looking for an easy to read, non-mathematical introduction to medical statistics that concentrates on the concepts, and not the formulae, then try:

·        Motulsky H. Intuitive Biostatistics (2e). New York: Oxford University Press, 2009.

·        Swinscow TDV. Statistics at Square One (9e). London: BMJ Publishing Group, 1997.

If you want to delve deeper into the topic of biostatistics, try:
