HSBH3018: Quantitative Research Methods in Health

Semester 1, 2021 [Normal day] - Camperdown/Darlington, Sydney

This unit will deepen your knowledge about design of observational and experimental studies in health, current issues in health research and statistical procedures for data analysis. We will discuss published studies and analyse our own data using correlation, linear regression, t-test, ANOVA, odds ratio, relative risk, etc., with understanding of fundamentals of statistical theory. You will develop the ability to draw a sound conclusion about the research question taking into account both statistical result and study design. You will learn to use Statistical Package for Social Sciences (SPSS), and how to write concise research reports. The unit will prepare you to be a critical reader of health research and to engage in further research training should you wish to do so.

Assessment summary

  • Group presentation (7%): Our aim here is to dig deeply into a small number of published papers. Together with your group, you will present a part of a paper, and another group will present other sections of the same paper.
  • Individual report based on our study (25%): We will conduct a study on ourselves, and you will write an empirical research report based on the study. The study topic and design will be discussed in class.
  • Quizzes (3% + 15%): Foundations quiz in Week 3 will assess online lectures and readings from Weeks 1-3 (part revision and part new material), which lay the foundation for further learning. Quiz conducted in class in Week 7 (15%) will assess your understanding of  concepts in research design and statistics introduced in the previous weeks. You will be asked to choose the appropriate analysis for a given research design, interpret output from a simple anaysis in SPSS (or statistical software of your choice), and interpret information from a published empirical study. Online practice quizzes are available.
  • Exam (50%): Questions will assess your familiarity with concepts, the depth of your understanding, and the ability to apply your knowledge to examples of published research; you will also be asked to interpret the SPSS output for procedures we covered in class. You must pass the exam in order to pass this unit of study.

More details can be found on Canvas.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

Use of generative artificial intelligence (AI) and automated writing tools

You may only use generative AI and automated writing tools in assessment tasks if you are permitted to by your unit coordinator. If you do use these tools, you must acknowledge this in your work, either in a footnote or an acknowledgement section. The assessment instructions or unit outline will give guidance of the types of tools that are permitted and how the tools should be used.

Your final submitted work must be your own, original work. You must acknowledge any use of generative AI tools that have been used in the assessment, and any material that forms part of your submission must be appropriately referenced. For guidance on how to acknowledge the use of AI, please refer to the AI in Education Canvas site.

The unapproved use of these tools or unacknowledged use will be considered a breach of the Academic Integrity Policy and penalties may apply.

Studiosity is permitted unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission as detailed on the Learning Hub’s Canvas page.

Outside assessment tasks, generative AI tools may be used to support your learning. The AI in Education Canvas site contains a number of productive ways that students are using AI to improve their learning.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Attendance and class requirements

Attendance:

LECTURES: We aim to have lectures recorded in multiple short segments, to be played in the allocated lecture time and interspersed with questions and activities. Lecture attendance is strongly recommended, in-person or virtual. Content accumulates quickly and we know from past experience that attendance makes it easier to keep up because you can ask questions and also get immediate feedback as you try to do activities/answer questions during the lecture.

TUTORIALS AND PRACTICALS: Attendance is compulsory, and your active participation is expected. Please don’t hesitate to ask questions in class.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Required readings

The following recommended textbooks are available from the library, but feel free to use other texts on research design and statistics if you are already familiar with them or have them.

Books 1, 3 and 4 below cover both research designs and methods for data analysis and have a lot of overlap but each has its own style and you may want to explore and choose one as your go-to source (also read brief descriptions given below). These three books are all available online.
Book 2 (Andy Field) is very different; it’s focused on statistics and the software package SPSS.; unfortunately, it is not available online but you may find older editions or some tutorials freely available online.

  1. Bruce N, Pope D & Stanistreet D (2018) Quantitative Methods for Health Research: a Practical Interactive Guide to Epidemiology and Statistics. Second edition.
