# PUBH5018: Introductory Biostatistics

This unit introduces students to statistical methods relevant in medicine and health. Students will learn how to appropriately summarise and visualise data, carry out a statistical analysis, interpret p-values and confidence intervals, and present statistical findings in a scientific publication. Students will also learn how to determine the appropriate sample size when planning a research study. Students will learn how to conduct analyses using calculators and statistical software. Specific analysis methods of this unit include: hypothesis tests for one-sample, two paired samples and two independent samples for continuous and binary data; distribution-free methods for two paired samples, two independent samples; correlation and simple linear regression; power and sample size estimation for simple studies; and introduction to multivariable regression models;. Students who wish to continue with their statistical learning after this unit are encouraged to take PUBH5217 Biostatistics: Statistical Modelling.

At the completion of this unit, you should be able to:

• LO1. choose appropriate measures to summarise data using tables and graphs
• LO2. create simple tables and graphs following guidelines for clear presentation
• LO3. determine and calculate the appropriate summary statistics to summarise different types of distributions
• LO4. understand and explain the concepts of sampling and sampling distributions
• LO5. choose the appropriate hypothesis test to apply based on the type of data collected and the design of the study
• LO6. calculate and interpret confidence intervals for various measures of effects (e.g. single mean, difference in means, difference in proportions)
• LO7. conduct and interpret simple hypothesis tests (e.g. one sample t-test, two-sample t-test, Chi-squared test)
• LO8. understand and explain the difference between statistical significance and practical importance
• LO9. carry out simple statistical methods using statistical software
• LO10. interpret the output produced by statistical software
• LO11. write concise descriptions that summarise the results from a statistical analysis
• LO12. determine the sample size requirements for simple studies.

## Unit outlines

Unit outlines will be available 1 week before the first day of teaching for the relevant session.
