Studying online

There are now 3 possible online modes for units:

Units with modes Online timetabled and Online flexible are available for any student to self-enrol and study online.

Units available in Online Restricted mode have been adapted for online study only for those students who require the unit to complete their studies and who are unable to attend campus due to COVID border closures. To be enrolled in a unit in Online Restricted mode, students should contact their Student Advising Office through askUWA and include which of the below criteria applies:

  • You are a student who is currently offshore and unable to enter Australia.

Content
This unit covers biostatistical methods commonly used in epidemiological and clinical research. It focuses on modern regression methods for means of quantitative variables, proportions (prevalences or risks) for binary variables, incidence rates for event counts, and survival curves for time-to-event variables. It also includes a few classical methods that are still in common use. Topics include analysis of variance (ANOVA) and multiple linear regression, 2 x K frequency tables, logistic regression, Poisson regression, Kaplan-Meier curves and Cox proportional hazards regression. The application of these methods to the analysis of data from cross sectional, case control, cohort and clinical studies is discussed and critical appraisal of published literature is included. Computing using SAS is an integral part of the unit.

Students who master the methods covered in this unit should be able to conduct many of their own analyses of health/medical research data.
Outcomes
Students are able to (1) correctly identify appropriate statistical methods for analysing data from different study designs with different responses.; (2) apply standard biostatistical methods commonly used in epidemiological and clinical research including modern regression methods for quantitative, binary and time-to-event outcome variables; (3) interpret the statistical content of articles in the epidemiological and clinical literature.; (4) use SAS software for reading data, data manipulation, calculating data summaries and for statistical analysis; (5) interpret the results from the application of biostatistical methods to data through the use of SAS; and (6) present results appropriately..
Assessment
Indicative assessments in this unit are as follows: (1) assignments (which involve computing) and (2) online tests. Further information is available in the unit outline.

Supplementary assessment is not available in this unit.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
