Brief Handbook Description: Health organisations cannot function effectively without computer information systems. Clinical data are stored and distributed in different databases, different formats and different locations. It requires a lot of effort to create an integrated and clean-up version of data from multiple sources, This unit provides basic introduction to the process and knowledge to enable the analysis of health data. The unit will be of interest to students seeking the understanding of the various coding standards in health industry, data retrieval from databases, data linkage issue, cleaning and pre-processing steps, necessary statistical techniques and presentation of results.

It will be valuable to those who want to work as health-related occupations, such as health informatics analysts, healthcare administrators, medical and health services manager or research officers in hospitals, government health agencies and research organisations. Having said that, a good understanding of health data analysis is a useful asset to all students.
Assumed Knowledge: Basic knowledge of Entity Relationship Modelling, database technology and SQL

Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.

Unassigned Outcomes
1. Student understands the role of data analysis in decision-making
2. Student understands the technical issues that are present in the collection of clinical data and the necessary of different pre-processing issues to clean-up a dataset for analysis.
3. Student can identify and select appropriate statistical techniques to summarise and analyse clinical data set, and able to articulate a justification of choice of methods.
4. Student can apply health concepts and terms to describe and analyse the role of a data analysis task.
5. Student can identify explicit and implicit requirements for carrying out a health data analysis task to meet stakeholder purposes
6. Student can communicate the results produced by an analysis pipeline, in oral and written form, including meaningful diagrams
7. Student can communicate the process used to analyse health data set, and justify the techniques & methods used.
8. Students can carry out (in guided stages) the whole design and implementation cycle of a simple health data analysis task

Assessment Description: Lab Activities: A student has to participate and engage in a few activities in the workshop (from w2-w12). The work in each week can worth up to 4 marks. The marks in five random weeks will be chosen as the final lab activities mark.

Presentation of Privacy. It is a group activity when members have to present on a specific privacy/ethical issue related to health data.

Project. A dataset is given such that each student has to perform necessary tasks and analysis to arrive observation and to infer conclusion. The project is to be staged in two milestones to help students achieving a final executive report.

Case Study (Statistics): Using statistical instrument to analyse a given health case.

Health Text Analytic: Students are asked to carry out text analysis tasks that have been discussed in the class.

Quiz: A quiz to assess the understanding of knowledge content of a student.
Grade Type Description
Standards Based Assessment Final grades in this unit are awarded at levels of HD for High Distinction, DI (previously D) for Distinction, CR for Credit, PS (previously P) for Pass and FA (previously F) for Fail as defined by University of Sydney Assessment Policy. Details of the Assessment Policy are available on the Policies website at . Standards for grades in individual assessment tasks and the summative method for obtaining a final mark in the unit will be set out in a marking guide supplied by the unit coordinator.
Minimum Pass Requirement It is a policy of the School of Computer Science that in order to pass this unit, a student must achieve at least 40% in the written examination. For subjects without a final exam, the 40% minimum requirement applies to the corresponding major assessment component specified by the lecturer. A student must also achieve an overall final mark of 50 or more. Any student not meeting these requirements may be given a maximum final mark of no more than 45 regardless of their average.
Policies & Procedures: IMPORTANT: School policy relating to Academic Dishonesty and Plagiarism.

In assessing a piece of submitted work, the School of Computer Science may reproduce it entirely, may provide a copy to another member of faculty, and/or to an external plagiarism checking service or in-house computer program and may also maintain a copy of the assignment for future checking purposes and/or allow an external service to do so.
