Biostatistics (PHCM2002)


Biostatistics is an introductory course to statistical methods used in the healthcare field. This course introduces students to the quantitative methods that are the cornerstone of public health research and evidence-based public health policy and practice. Students will learn about the principles of statistical reasoning, underlying assumptions, and methods to analyze and interpret data.

Credit points

This is a core course in the Bachelor of International Public Health (3880) comprising 6 units of credit towards the total required for completion of the study program.

Mode of study

Fully online.


TThere are no pre-requisites for this course, however, it is advised that you have a solid understanding of mathematics.

Course aim

The course aims to introduce students to key biostatical concepts, and to develop biostatistical skills to a level that allows independently analyse data and the production of meaningful information.

Course learning outcomes

Upon completion of this course, students will be able to:

  • Identify and apply appropriate statistical tests to analyse data and produce information.
  • Compare, critically judge and justify why one statistical method should be used over another.
  • Interpret and explain the results of statistical analysis.
  • Relate the practice of biostatistics to real world situations.
Learning and teaching rationale

This course has been designed to support you gain the fundamental knowledge and skills for applying biostatistics. This course uses learning activities and assessment tasks that reflect the learning outcomes of the course and that draw on real-world examples. This course applies a ‘constructivist approach to teaching and learning. That is, lessons, activities, and assessment tasks have been developed to align with the course’s learning outcomes. The material you will cover will first introduce a concept or technique before demonstrating it. You will then be required to apply the concept yourself and relate it to real-world situations. It is anticipated that you will not only develop technical skills in biostatistics but also understand how these skills are used to address real world public health problems.

It is expected students will spend 10-12 hours per week preparing for, completing assessments tasks, and actively participating in this course. If you find statistics challenging, you should allow additional time.
