STATS 7056 - Biostatistics

North Terrace Campus - Semester 2 - 2018

Biostatistics is fundamental to contemporary biomedical research. It plays a central role in evaluating new treatments for cancer and heart disease, in measuring survival following lung and liver transplants, in monitoring and predicting the spread of epidemics including HIV/AIDS and swine `flu, and much more. Biostatistics aldo emerged in recent years as a key collaborating discipline in bioinformatics following the sequencing of the human genome. You will learn that expert advice from biostatisticians is crucial for pharmaceutical drug development, health-data surveillance and analysis, and for informing government debate and health policy. This course provides an introduction to the design and analysis of clinical trials, epidemiological studies, and methods for the analysis of biostatistical data. Topics covered are: Clinical trials, Phase I to Phase IV trials, key aspects of study design: the Data and Safety Monitoring Board, trial types; justification of randomization, including ethical considerations; methods of randomization, unrestricted and restricted randomization, random permuted blocks, biased coin designs, stratification, minimization; randomization tests, permutation and bootstrap t-tests; calculating trial size, fixed and group sequential trials; power calculations for continuos and binary responses; more complex trial designs, crossover slinical trials and bioequivalence trials. Epidemiology; cohort, case-control and related observational studies; the advantages and disadvantages of each type of study; models for disease association, risk difference, relative risk, odds, ratio, attributable risk; the analysis of binary outcomes for retrospective and prospective data. Inference for 2x2 tables, the analysis of 2x2 tables and appropriate test procedures. Wald test, Likelihood Ratio test, profile likelihood; conditional inference for 2x2 tables; Fisher's Exact test: McNemar's test for matched pairs data; Mantel Haenszel test for comparing several 2x2 tables. Case studies on drug trials, heart disease, cancer, HIV/AIDS, leukaemia and environmental health.

  • Learning & Teaching Activities
    Learning & Teaching Modes
    The lecturer guides the students through the course material in 24 lectures. Students are expected to prepare for lectures by reading the printed notes in advance of the lecture, and by engaging with the material in the lectures. Students are expected to attend all lectures, but lectures will be recorded to help with occasional absences and for revision purposes. In the fortnightly tutorials, students will discuss their solutions in groups and present them to the class on the board. These exercises will be further supplemented by the fortnightly computing practical sessions during which students will work under guidance on practical data analysis and develop computing skills using R. A series of five homework assignments builds on the tutorial and practical material and provides students with the opportunity to gauge their progress and understanding of the course material.

  • Student Feedback

    The 最新糖心Vlog places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

    SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the 最新糖心Vlog to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student鈥檚 disciplinary procedures.

The 最新糖心Vlog of Adelaide is committed to regular reviews of the courses and programs it offers to students. The 最新糖心Vlog of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
