Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Assessment Tasks

This information will not be available until 8 weeks before term.
To see assessment details from an earlier availability, please search via a previous term.

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Source: Student Evaluation
Feedback
Maybe a lecture video going through a past exam?
Recommendation
Consider creating some videos covering the styles of exam questions.
Action Taken
Two special videos were made for the exam in the 2018 offerings. The first video gave general comments about the exam. The second video gave specific comments about each question on the upcoming exam. Also at least one relevant past exam question was completed in each weekly online Zoom tutorial which was recorded and made available on the STAT11048 webpage on a weekly basis. In 2018 Term 2, a student commented on these videos in the Unit Evaluation saying: "... also the videos about the exam made me more prepared and overall helped calm my nerves and enabled me to perform better in the exam."

Feedback
Calculations should be used on calculator much more in lectures.
Recommendation
Run some Zoom sessions and/or create some videos specifically on calculator use. There may already be videos available online for some of the more common models. These could be identified and linked.
Action Taken
Calculations were performed using calculators in lectures. Also the recorded weekly online Zoom tutorials demonstrated calculator use. Additional calculator resources were located/created and made available to students on the unit's webpage.

Feedback
The weekly unit content could be placed under different sub-headings in the unit's Moodle page. "Moodle is near impossible to navigate on mobile devices, with this strange setup, why not stick to the tried and proven method of expandable things for each week, down the page? The tiny number links for each week are impossible to click on the phone or iPad even, especially with them all being so close together, try to click on week 1 and end up on Week 8 stuff."
Recommendation
There were quite a few comments on the Moodle page set out. This unit differs from others in that the links to the weekly work are in one block in the right column, not down the middle column as is more usual. This seemed to especially difficult to navigate on a mobile device. Consider revising the layout of the page to make it more user-friendly.
Action Taken
The Moodle webpage was redesigned to make it more user-friendly for mobile devices and similar to other CQUni Moodle unit webpages with collapsible weeks in the middle column.

Feedback
The current textbook is too old (a 2010 edition) and has a strong focus on US Business applications of statistics.
Recommendation
A new textbook is to be prescribed with a focus on Australian and New Zealand business applications of statistics and which has a more recent edition.

Feedback
The Study Guide needs to be revised and updated.
Recommendation
A new edition of the Study Guide will be produced.

Feedback
The lecture videos need updating as there are some technical issues in the current videos and they use an old version of the Study Guide and an old version of the STAT11048 webpage.
Recommendation
A new set of lecture videos will be recorded using the new edition of the Study Guide.
Action Taken

Feedback
Some students find the maths very challenging in this unit. There is a need for more help for students who have little or no background in maths.
Recommendation
Identify additional resources that can be provided to students, e.g. online or face-to-face tutorials, to cover background math topics.
Action Taken
