Assessment criteria

High Distinction 85-100 Outstanding or exemplary performance in the following areas: interpretative ability; intellectual initiative in response to questions; mastery of the skills required by the subject, general levels of knowledge and analytic ability or clear thinking.
Distinction 75-84 Usually awarded to students whose performance goes well beyond the minimum requirements set for tasks required in assessment, and who perform well in most of the above areas.
Credit 65-74 Usually awarded to students whose performance is considered to go beyond the minimum requirements for work set for assessment. Assessable work is typically characterised by a strong performance in some of the capacities listed above.
Pass 50-64 Usually awarded to students whose performance meets the requirements set for work provided for assessment.
Fail 0-49 Usually awarded to students whose performance is not considered to meet the minimum requirements set for particular tasks. The fail grade may be a result of insufficient preparation, of inattention to assignment guidelines or lack of academic ability. A frequent cause of failure is lack of attention to subject or assignment guidelines.

Quality assurance

For the purposes of quality assurance, Bond University conducts an evaluation process to measure and document student assessment as evidence of the extent to which program and subject learning outcomes are achieved. Some examples of student work will be retained for potential research and quality auditing purposes only. Any student work used will be treated confidentially and no student grades will be affected.

Study information

Submission procedures

Students must check the [email protected] subject site for detailed assessment information and submission procedures.

Policy on late submission and extensions

A late penalty will be applied to all overdue assessment tasks unless an extension is granted by the subject coordinator. The standard penalty will be 10% of marks awarded to that assessment per day late with no assessment to be accepted seven days after the due date. Where a student is granted an extension, the penalty of 10% per day late starts from the new due date.

Policy on plagiarism

University’s Academic Integrity Policy defines plagiarism as the act of misrepresenting as one’s own original work: another’s ideas, interpretations, words, or creative works; and/or one’s own previous ideas, interpretations, words, or creative work without acknowledging that it was used previously (i.e., self-plagiarism). The University considers the act of plagiarising to be a breach of the Student Conduct Code and, therefore, subject to the Discipline Regulations which provide for a range of penalties including the reduction of marks or grades, fines and suspension from the University.

Bond University utilises Originality Reporting software to inform academic integrity.

Feedback on assessment

Feedback on assessment will be provided to students within two weeks of the assessment submission due date, as per the Assessment Policy.

Disability support

If you have a disability, illness, injury or health condition that impacts your capacity to complete studies, exams or assessment tasks, it is important you let us know your special requirements, early in the semester. Students will need to make an application for support and submit it with recent, comprehensive documentation at an appointment with a Disability Officer. Students with a disability are encouraged to contact the Disability Office at the earliest possible time, to meet staff and learn about the services available to meet your specific needs. Please note that late notification or failure to disclose your disability can be to your disadvantage as the University cannot guarantee support under such circumstances.

Additional subject information

As part of the requirements for Business School quality accreditation, the Bond Business School employs an evaluation process to measure and document student assessment as evidence of the extent to which program and subject learning outcomes are achieved. Some examples of student work will be retained for potential research and quality auditing purposes only. Any student work used will be treated confidentially and no student grades will be affected.

Subject curriculum

A review of descriptive statistics, including numerical and graphical summaries of location, spread and symmetry. Also includes the definition and structure of probability models.

A review of basic probability rules, including conditional probability and Bayes theorem, joint events and independence. The importance and usage of the Law of Total Probability is introduced.

An introduction to random variables, including distributions, moments, percentiles and various generating functions.

Introduces the properties and relationships of common discrete random variables, including binomial, Poisson, negative binomial and hypergeometric.

An exploration of the properties and relationships of common continuous random variables, including normal, log-normal, Cauchy, Student’s t, uniform, exponential, gamma, Weibull, Pareto, beta, Fisher F and Burr. The change of variable method is introduced to facilitate calculations regarding the relationships between various distribution and density functions.

Introduces the structure, definition and properties of joint distributions, marginal distributions and conditional distributions.

Basic distribution theory, including the use convolutions is introduced. Derivation of the density functions of the Student’s t-distribution, beta distribution and Fisher’s F-distribution are also covered. In addition, definition and discussion of the properties of random sums and compound distributions is presented.

Various distributional properties of multivariate normal random variables are presented and the Central Limit Theorem is introduced first via the normal approximation to the binomial distribution with continuity correction and then more generally using cumulant generating functions. In addition, Cochran’s Theorem is introduced.

The concepts of point estimation, including the method of moments and maximum likelihood are explained. The likelihood function is introduced as are the concepts of mean-squared error and loss functions. In addition, the principles of sufficiency and optimality in constructing estimators are introduced and discussed, and lead to presentation of Bayesian and resampling-based frameworks for estimator construction and assessment.

Definition and principles of construction of interval estimates are introduced and investigated. These include standard pivot-based intervals as well as both Bayesian highest posterior density regions and bootstrap-based non-parametric confidence intervals.

The structure and properties of hypothesis tests including definitions of size, power, one-sided versus two-sided testing and optimal test structure are considered. These principles are applied to the case of maximum likelihood. In addition, the Pearson chi-squared goodness of fit test for a categorical response variable is introduced.
