General information about University computer laboratories is available at
As an enrolled student, you will have access to the University’s on-line teaching facilities. This is an implementation of the Blackboard system called MyUni. MyUni is accessible from the University of Adelaide’s home-page: www.adelaide.edu.au
You will need your student login name and a password.
If you do not have access, then either you are not enrolled or the administrators of MyUni do not know of your enrolment. Please call the Student Centre on 8313 5208 (Uni extension 35208) or the MyUni help desk on 8313 3335 (Uni extension 33335) for assistance with MyUni difficulties.
Selected documentation for this course will be placed on MyUni including lecture overheads, lecture recordings, and tutorials. Note also that Announcements about a course are often made on the relevant page of the MyUni site for the course. For example, notifications of a change in lecture venue, updates on availability of course material etc. will be made on the MyUni site.
We assume that you have access to e-mail and that your address is the University of Adelaide student address that was assigned to you on enrolment. This is of the form:
A notice to a student by e-mail is considered to have been received and read by the student unless there is a transmission error and the postmaster bounces the message back to us. As discussed above, the Announcements page of the MyUni site for this course will also display relevant notices from time to time, so it is in your interest to check your student e-mail and to log on to MyUni regularly.
Learning & Teaching Activities
Learning & Teaching Modes
There are a number of teaching and learning modes in this course. The course lectures provide basic factual information and concepts in an introduction to biostatistics. Due to the limited timeframe, not everything will be covered in lectures. Lectures are intended to supplement material covered in the readings. Lectures will be supported by interactive tutorials which are designed to develop and clarify topics covered in the readings and lectures. These are generally problem solving sessions and students are required to complete as many questions as possible prior to their allocated tutorial. Assignments provide an opportunity to undertake exploratory and in-depth analysis of some key concepts introduced in the course. Finally, the exam will assess the extent to which students have developed their biostatistical understanding through the course.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.
As a general rule in any university course, you will need to allow a minimum of three independent study hours for every hour undertaken in formal class work contact. This means that, for Introduction to Biostatistics, you will need to set aside at least a further six hours per week for reading around topics, preparation for tutorials, and submitting your assignments. You are urged to bear this in mind when planning your university timetable, particularly if you are also engaged in paid employment. In our experience, students may not be able to demonstrate their full capacity if they are working full-time and studying full-time. Students are expected to attend all lectures and tutorials as completion of readings alone will almost certainly not provide sufficient material to enable a pass.
a) Students are expected to complete readings prior to the lecture for which they are assigned and, where appropriate, to have worked through tutorial problems before the scheduled tutorial, with the exception of the tutorial in week 1.
c) Students are expected to attend all lectures and tutorials as completion of readings alone will almost certainly not provide sufficient material to enable a pass.

Specific Course RequirementsN/A
Small Group Discovery ExperienceN/A
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.
Assessment Task Assessment Type Weighting Learning Outcome(s) being addressed Assignment 1: Descriptive Statistics Summative 20% 1, 3, 4 Assignment 2: Inferential Statistics Summative 20% 1-4 Examination Summative 60% 1-4
In the event that a student does not pass, a supplementary examination (which may be viva voce)
and/or further set work (at the discretion of the course co-ordinators) may be offered. A student
offered such supplementary assessment may obtain one of two grades: Pass (with a maximum score of 50% recorded) or Fail. The mark shall be awarded on either (i) the results of the supplementary assessment only, or (ii) the combined results of the course assignments and supplementary assessment, whichever advantages the student most. In the event of a Fail after supplementary assessment, the entire course must be repeated.
Assignments and written work should, whenever feasible, be typed or word-processed, although work comprising algebraic notation is acceptable in handwritten form if neat and legible.
Assessment Related Requirements
To pass this course, a student must submit both assignments and score at least 50% overall (assignments and examination).
All assessment tasks will be distributed via hardcopy in lectures. All assessment tasks will be assessed according to the University's M10 scheme.
Assignments can only be submitted in hardcopy form either to someone at Reception or through the slot in the locked box at the Discipline of Public Health, Level 7, 178 North Terrace. The appropriate cover sheet must be attached to each assignment. These coversheets are available through MyUni. Each student submitting an assignment must also sign and date the designated class list (for this course and this assignment) which will be available at Reception. Assignments must be submitted by 4.00pm on the due date. The locked box will be emptied every day at this time.
Multiple pages should be stapled at the top left hand corner, irrespective of whether a protective plastic sleeve is used. Each page should be numbered and the total number of pages should appear on each page (e.g. “page 2 of 4” or “2/4”). The first page should bear the student’s name and student number; each subsequent page should bear, at least, the student’s initials. It is prudent to keep a photocopy of your assignment.
An assignment may not be submitted by e-mail or by fax and should not be given to lecturers or tutors in an ad hoc fashion at the time of lectures or tutorials. Marked assignments can be collected from the Discipline of Public Health.
Must be requested, at the latest, by the last working day before the due date of submission.
Will generally be granted only on medical or genuine compassionate grounds.
Only the course coordinator(s), or a person authorised by him or her, may grant extensions.
Documentary supporting evidence such as a medical certificate or a police report (in the case of lost computers, car & household theft etc.) will usually be required when requesting an extension.
Students submitting examinable written work who request (and receive) an extension that takes them beyond the examination period are advised that there is no guarantee that their grades will be finalised “in time for graduation” for post-graduate courses or “in time to meet usual University deadlines”.
Marks will be deducted when assignments for which no extension has been granted are handed in late. All assignments, including those handed in late, will be assessed on their merits. In the case of late assignments, marks will then be deducted from the mark awarded, at the rate of 5 percentage points of the total possible per day. e.g. If an assignment which is 2 days late is awarded 65% on its merits, the mark will then be reduced by 10 (5 marks per day for 2 days) to 55%. If that same assignment is 4 days late its mark will be reduced by 20 (5 marks per day for 4 days) to 45% etc.
The Discipline reserves the right to refuse to accept an assignment that is more than 7 days late.
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.
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.

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.
