### Description

The purpose of this subject is to provide students with fundamental concepts in biostatistics, an understanding of biostatistical reasoning and its application to research studies, and the ability to evaluate health care related practice and research output critically. This subject introduces statistical concepts of data presentation, data management, confidence intervals, sample size and power, descriptive statistics, and bivariate statistical analyses.

The subject does not focus on computing skills, but instead on the interpretation of research output and the appropriate use of analysis methods. On completion of this subject, students are able to select the correct statistical analysis tests appropriate to research questions and are able to contribute to study design by undertaking power and sample size calculations.

### Subject learning objectives (SLOs)

Upon successful completion of this subject students should be able to:
A. Utilize basic biostatistical concepts and analytical techniques to determine the effectiveness and/or efficacy of health care interventions, practices, or services Compare and contrast different methods of data collection and statistical analysis Generate (using a statistical package) and interpret descriptive statistics and bivariate statistical analyses Determine the appropriate sample size and statistical power for study design

### Course intended learning outcomes (CILOs)

This subject also contributes specifically to the following graduate attributes:

• Demonstrate reflective critical thinking to enable critical appraisal of current practice, policy and research with the aim to enhance health care and health care outcomes, and transform health (1.0)
• Critique, interpret and synthesise epidemiological outcomes and statistical findings at a superior level to inform the surveillance, management and prevention of disease and illness, and promotion of health for the complex issues inherent in public health (1.1)
• Design and apply research methods to a variety of public health problems (1.2)
• Communicate effectively and appropriately in challenging, complex and diverse situations (4.0)

### Teaching and learning strategies

In this online subject, students will participate in two face-to-face workshops and weekly online teaching and learning
activities distributed over a period of six weeks. There is an expectation that students complete all online activities to get the most out of the subject. Students will be provided with engaging learning activities to deepen their understanding of biostatistical reasoning and its application relevant to health care and public health. Online activities and face-to-face workshops will offer students opportunity to conduct statistical analyses, interpret the results, engage with statistical software, and critique statistical analysis results in published studies. Students are expected to work independently and to engage with other students and teachers online through discussion forums and other interactive activities such as Zoom meetings.

Assessments are designed to complement the learning by providing students with the opportunity to practically apply and track their understanding of fundamental concepts and techniques relevant to biostatistics. Students will receive feedback from teaching staff in online discussions and activities and on assessment tasks.

### Content (topics)

• Data collection and presentation;
