Assignment

This assessment aims to develop and gauge student understanding of the key topics covered so far by answering the following questions. Answering these questions will help you build some understanding for the next assessment item as well as for the entire subject. It is expected that answers to the assignment questions be succinct (i.e. precise and concise) with all sources of information fully referenced as per APA referencing style. You have to reference the text book and any additional material you have used in your answers.
Note that the guide for APA referencing is provided in the resources section of Interact site of this subject.

Answers MUST be written in your own words. No marks will be awarded for any answer that contains more than 10% direct quote (referenced or unreferenced). One or two sentence answers will be too short and only receive low marks. Answers longer than 1.5 pages (12 point font, single line spacing) may incur a penalty if too much non-relevant information is stated. For mathematical questions it is expected that you show intermediate steps of your working. Just stating the correct solution will result in low marks, on the other hand if the working is correct and you only made minor mistakes, you will still be awarded marks, even though the final answer is wrong.
