HSBH3018: Quantitative Research Methods in Health

Semester 1, 2020 [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 section of a paper, and other groups 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%): A smaller online quiz in Week 3 will assess online lectures and readings from Weeks 2 and 3 that are partly revision, and 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.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

For more information see guide to grades.

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.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

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: Attendance of most lectures is required (but note that Week 3 lecture is online). There will be activities and worksheets to complete during the lecture and handed in at its end. Submission of worksheets will count as lecture attendance. You can miss two lectures provided that you submit the worksheet at the beginning of the tutorial in the same week. Tutorials attendance is compulsory and a roll will be taken.

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

All readings for this unit can be accessed through the Library eReserve, available on Canvas.

The following recommended textbooks are available from the library, but feel free to use other texts on reearch design and statistics:

  • Field, A.P. (2014). Discovering statistics using IBM SPSS statistics: and sex and drugs and rock 'n' roll. (4th ed.). London, SAGE Publications.
  • Saks, M. & Allsop, J. (2013) Researching health: Qualitative, quantitative and mixed methods. London: Sage. You used this textbook in HSBH1007/2007.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

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

  • LO1. understand social context of research and that research questions arise from theory and practical needs
  • LO2. distinguish research findings (facts) from interpretations by researchers or the media
  • LO3. understand basic design characteristic of health studies
  • LO4. understand and apply basic concepts of descriptive and inferential statistical
  • LO5. identify an appropriate method of data analysis for a given (simple) study design
  • LO6. conduct and interpret simple data analysis using SPSS (or other statistical software)
  • LO7. present research findings clearly and succinctly in written and oral form

This section outlines changes made to this unit following staff and student reviews.

This year for the first time we introduced formative group presentation prior to the final, marked presentation because any learning process naturally benefits from feedback (we previously offered feedback on the individual empirical report before its final submission, and students were quite happy about that).
