Learning Outcomes
Course Learning Outcomes
On successful completion of this course, students will be able to
1. demonstrate their understanding of the mathematics of statistical inference;
2. derive the distributional results needed for statistical inference;
3. conduct appropriate hypothesis tests for comparing two means and for regression;
4. recognise that hypothesis tests, regression and analysis of variance belong to the same theory of linear models;
5. demonstrate their understanding of the theory of maximum likelihood estimation for a scalar parameter;
6. analyse a variety of datasets and fit linear regression models using R; and

Learning Resources
Required Resources
There are no required resources for this course. Lecture notes are provided and R and RStudio are freely available.Recommended Resources
We will refer to the following two text books throughout the course. Both books contain material directly relevant to the content and objectives of the course, and are available in the Barr Smith library:
J. A. Rice: Mathematical Statistics and Data Analysis. Third edition (2007).
D.D. Wackerly, W. Mendelhall and R.L. Scheaffer: Mathematical Statistics with Applications. Seventh edition (2008).Online Learning
This course uses MyUni for providing electronic resources, such as lecture notes, assignments, tutorial and practicals. It is recommended that the students make appropriate use of these resources.

Learning & Teaching Activities
Learning & Teaching Modes
The lecturer guides the students through the course material in 35 lectures. Students are expected to prepare for lectures by reading the printed notes in advance of the lecture, and to engage with the material in the lectures. Interaction with the lecturer and discussion of any difficulties that arise during the lecture is encouraged. Students are expected to watch the lecture videos and study the lecture notes. In the fortnightly tutorials, students are encouraged to discuss their solutions with each other. 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. Four homework assignments build on the tutorial and practical materials and help students strengthen their understanding of the theory and practical work, and gives them the opportunity to gauge their progress and understanding of the course material.Workload
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

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.

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.
