The assessment strategy is designed to allow students to demonstrate their acquired knowledge and skills to appropriately choose, implement, report, and critically appraise statistical techniques and methods, as applied to healthcare and biomedical research and practice.
Through both the formative and summative assessment, students will demonstrate their understanding and exploration of key concepts, principles and applications of statistical techniques in healthcare and biomedical research and practice, while the summative assessment will allow students to demonstrate their gained knowledge and skills in properly choosing statistical methods, implementing the chosen methods on statistical software, reporting the methods and results, and critically appraising the limitations of their analyses.
Thus, the summative assessment for this module consists of:
- Three analysis coursework reports submitted at three timepoints during the module, following practical workshops, as PDF file and statistical programming code. The coursework involves submission of the statistical programming code and a summary report of the methods and results of the analyses conducted during the practical sessions (each accounting for 10% of the final grade, totalling in 30% of the final grade, individual work). The coursework may include additional probing questions that are designed to allow students to demonstrate their understanding of key statistical concepts and principles learned in the weekly lectures (addressing learning outcomes 1-6).
- Workshop presentation and participation in discussions (10%, individual work). This will include a 10 minutes presentation followed by 5 minutes of questions and discussion (addressing learning outcomes 3, 6, and 7).
- Two written and statistical programming assessments (30% each, individual work) submitted as PDF file and statistical programming code. Each assessment will involve one large or several smaller piece(s) of statistical analysis work. Each piece of work will involve a general description of the task and its specific aim(s)/goal(s) and the raw or intermediate data that are necessary to carry out the work. Each of the assessment is expected to be ~1500-2000 words and include a number of figures, plots and tables. Students will be required to choose and implement appropriate statistical method(s) to achieve the aim(s)/goal(s), properly report their chosen method(s) and analysis results, and critically appraise the limitation of their method(s) and analytical work (addressing learning outcomes 1-6).
Students will submit an outline of their planned presentation for workshop; feedback and guidance will be provided to ensure students are on the right track.
Students will receive written feedback from the module lead and/or teaching assistant on each of the assessment elements; this includes the weekly coursework, workshop presentation slides, and the writing and statistical programming assessments. Verbal, formative, feedback will also be provided following the workshop presentation as well as during the practical sessions.

Methods of Teaching / Learning
The learning and teaching strategy is designed to ensure that students achieve the module’s learning outcomes and develop competencies in the corresponding aspects of the curriculum framework (employability, digital capabilities, global and cultural intelligence, and resourcefulness and resilience). The module is designed in a way that builds upon concepts parallelly taught by the Big Data in Biomedicine and Health module, by implementing these through real-world examples and data.
This module will be taught in a series of lectures and practical sessions. The lectures will introduce key concepts and principles of statistical methods commonly used in healthcare and biomedical research and practice, followed by tutorials on implementing the methods on statistical software (e.g., R) and discussion of real-world examples and limitations of applying the methods to evaluating/improving the outcomes of health interventions or the efficiency, productivity and quality of healthcare processes and systems. This strategy will ensure students gain both a firm grounding in the theoretical aspects of the covered topics, but also the practical implementation skills expected to be held by future data scientist and informaticians. Statistical software and digital resources will be fully integrated within the lectures, and students will have the opportunities to co-develop and test statistical programming code with the module lead and their peer students. The lectures will also provide students with the skills of reporting statistical methods and results, including the generation of high-quality tables and figures and appropriately writing the “Methods” and “Results” sections in reports and publications.
Students will further practice and develop their statistical skills in computer-based practical sessions. The sessions will provide students with the opportunity to handle real health data and experiment with statistical methods learned in the lectures. In addition, students can practice the reporting of their statistical analyses, including writing the codes to generate plots and figures.
As a major part of the weekly coursework, students will be required to summarise and report the methods and results of their works in the practical sessions and critically appraise the limitations of their analyses. Students will be encouraged to complete these sessions independently, utilising the statistical techniques, software and the digital and online resources introduced in the lectures.
Written feedback will be provided by the module lead and/or teaching assistant, and discussions will be organised weekly for students to reflect on their work. The practical sessions will facilitate students in developing key digital capabilities that are highly sought after by employers across sectors. These sessions will further empower students in learning and utilising online resources to help with solving applied statistical problems.
In addition to lectures and practical sessions, a workshop will be organized to provide students with the opportunity to teach-learn from each other and explore an interested topic with greater depth. The topic of the workshop will be voted on by students from a list of candidate topics prepared by the module leader. Students will then prepare a presentation, which will be delivered during the workshop followed by questions and discussions.
The learning and teaching methods will therefore include:
- Computer-based laboratory practical sessions
- A workshop
- Weekly homework
- Reading and self-learning under the module leader’s guidance
- Written assessments as described below.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
