Learning Outcomes
Course Learning Outcomes
1. Explain the mathematical basis of the linear model and its extensions to the generalised linear model and non-linear models.
2. Use the open sources programming language R for the analysis of data arising from surveys and designed experiments, and for the analysis of time series.
3. Write a report of a statistical analysis that explains the purpose of the investigation; summarises the findings of the investigation; and documents evidence for the conclusions.
4. Explain the role of statistical modelling in discovering information; making predictions and decision making in a range of applications including engineering, science, business, and social science.University Graduate Attributes

Specific Course Requirements
A background in probability and statistics as provided by a typical introductory course. Some experience of using R will be helpful, but not essential. If you have not used R before, it would be a good idea to try doing so before the course starts. You might find either of Introductory Statistics with R, Dalgaard P, 2002, or A Beginner's Guide to R, Zuur AF, 2009, which are available from the Barr Smith Library, useful.Small Group Discovery Experience
You will be asked to work as part of a small group on two short presentations of applications of statistical modelling. -
Assessment
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.

Attendance and active participation at five out of six tutorials contributes 5% to the assessment for this course.
The practicals are based on the use of the programming language R in a computer suite. Attendance and evidence of making substantial progress through the practical exercise contributes 5% to the assessment for this course.
The presentation talks are group exercises, and each member of the group is expected to present part of the talk to the class and any guests. Each presentation contribues 5% to the assessment for this course.
The first presentation will be of an application of statistical modelling from the media: news websites or newspapers; magazines including for example the Scientific American and the New Scientist.
The second presentation will be of an application of statistical modelling from an archived journal in any discipline.
Presentations should not be based on articles from Significance or cases from text books.
Five assignments contribute 20%.
The written examination contributes 60%.Submission
All written assignments are to be submitted to the designated hand-in boxes in the School of Mathematical Sciences with a signed cover sheet attached.Course Grading
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.

Student Feedback
The University 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 University 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.

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’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
