Overview
An understanding of experimental design, statistical methods, ethics and the ability to critically analyse scientific reports is essential for graduates in the sciences. In this unit, you will study experimental design, ethics and commonly used statistical procedures. You will be introduced to hypothesis testing and experimental design, parametric and non-parametric analyses, one, two and multi sample analyses (including one way, two way, and nested ANOVA designs, as well as multivariate analyses), correlation and regression, and data transformation. The learning and teaching strategy uses a clear, conceptual approach, which assumes that you have little or no statistical background.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability. See details in the Assessment Policy and Procedure (Higher Education Coursework).
Offerings For Term 2 - 2022
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).
Recommended Student Time Commitment
Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Overview
Assessment Grading
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%). Consult the University's Grades and Results Policy for more details of interim results and final grades.

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.
Feedback from Moodle feedback
One student commented that no timely feedback or responses were provided, and that communication from the lecturer was slow.
This comment is perplexing given the weekly additional live Zoom sessions run through term, and the focus on fast return of marked work with individual feedback (longest period from submission to return was 7 days). All feedback is considered toward continual improvement of timely communication and feedback.
Feedback from Moodle feedback Email
Students expressed their appreciation for the format of the lectures being in shorter 'bite-sized' units of information that they could learn from before building upon with the subsequent lecture.
Retain this format of content delivery for future offerings.

Please note that the lecture and assessment content for this unit is delivered online, and as such, will require your dedication to keep up with the provided learning materials throughout term. The Moodle page will be a central resource for accessing content, assignment instructions, as well as the teaching staff. Additional live "drop in, drop out" Zoom sessions will be run throughout term as an opportunity for your to ask questions and get live feedback from the teaching staff. The schedule for these live Zoom sessions will be made available on Moodle. They are not compulsory to attend, but instead offer an additional forum for you to gain clarity about unit content and assessment requirements. There is no residential school for this unit, but there will be an 'at home' practical assessment that you will need to complete.
1 Written Assessment
You are required to critique a summary description of a research project, using the knowledge you have gained so far in the unit.
You will be provided with a summary description of a research project that will contain conceptual and technical flaws in the approach to the research (including context/justification), methodology/experimental design, logic of thought, analysis and/or conclusions for you to consider. In your critique submission, you will need to:
· Identify the flaws in approach, logic, methodology, analytical procedures, interpretation/conclusions,
· Describe why you consider it a flaw, and
· Present your specific solution to remedy the flaw, if possible (if you think a solution is not possible, explain why).
Note that statements such as "The entire methdology wasn't presented", "The summary is written in the first person", and other such broad perceived flaws won't attract any marks since this is a summary of a project, and not the full formal description (i.e. marks are awarded for focusing on the scintific validity of what is presented in the summary, and not what isn't).
You may present your findings as either regular prose (i.e. akin to an essay or report), as an expanded list of dot points, or as a table. Please choose whichever written format you consider will be most suited to conveying your thoughts.
There is a limit of 1000 words (+/- 10%) for this assignment.
Week 6 Monday (22 Aug 2022) 11:45 pm AEST
Please submit your work as a Word document via Moodle. No PDF files will be accepted.
Week 8 Monday (5 Sept 2022)
Your work will be returned to you via Moodle.
This assessment is worth 25 % of your overall unit grade, and will be marked according to the following criteria:
Flaw identification (33.33 % of final mark)
Reasoning why you think it's a flaw (33.33 % of final mark)
Solution to the flaw (33.33 % of final mark)
- Describe the uses, pitfalls and limitations of parametric and non-parametric statistical tests
- Know when experiments require ethical clearance and explain the basic principles of ethical experimentation
- Critique scientific reports and research proposals in terms of the quality of their experimental design
- Communication
- Problem Solving
- Critical Thinking
- Information Literacy
- Ethical practice
2 Practical Assessment
You are required to evaluate the data acquired from three different experiments, suggest an appropriate statistical test for each, do the tests using the IBM SPSS statistics computer program, and interpret your results. An assessment template with the data and questions to answer will be provided on the Moodle site. You will be able to type your answers directly into this template, and resubmit the file to Moodle for assessment. You will need to download/access the SPSS computer program for this assessment. Instructions on how to do this will be provided during the term.
Week 11 Monday (26 Sept 2022) 11:45 pm AEST
Please submit your work as a Word document via Moodle. No PDF files will be accepted.
Week 12 Friday (7 Oct 2022)
Your work will be returned to you via Moodle.
This assessment is worth 25 % of your overall unit grade, and will be marked based on providing correct answers to the questions asked for each of the three data sets provided to you. Each data set has 8 questions, with one point awarded per correct answer. Broadly, questions are focused on choosing the appropriate statistical test for the data provided, using it correctly, and providing the correct intepretation of the test.
- Choose an appropriate statistical test for a set of data
- Correctly use software programs for analysing scientific data
- Communication
- Problem Solving
- Critical Thinking
- Information Technology Competence
3 Online Quiz(zes)
You will be required to complete an end of term online quiz that will test your knowledge of the entire content of the unit. The quiz will be in a similar format to a traditional end of term exam, requiring you to complete the task within a defined period of time (3 hours will be allocated). Some basic calculations will be required as practiced in the lecture content.
PLEASE NOTE: The date listed below for this assessment is a placeholder date only. The exact day of the quiz will be finalised ASAP during term once appropriate timetabling has been considered to avoid clashes of multiple similar assessments during the exam weeks. This date will be advertised on Moodle when known.

Review/Exam Week Monday (10 Oct 2022) 9:00 am AEST
Please complete the quiz on Moodle as instructed.
Exam Week Friday (21 Oct 2022)
Your quiz will be marked online through Moodle.
This quiz is worth 50 % of your overall unit grade. Each question in the quiz will be worth a different amount of marks depending on its complexity. Please attempt ALL questions to ensure you can get the highest mark possible. It is usually a good strategy to first attempt those questions that have the highest marks allocated to them, in case you run short of time. Examples of past similar questions will be provided for you as a study aid on Moodle.

As a CQUniversity student you are expected to act honestly in all aspects of your academic work.
Any assessable work undertaken or submitted for review or assessment must be your own work. Assessable work is any type of work you do to meet the assessment requirements in the unit, including draft work submitted for review and feedback and final work to be assessed.
When you use the ideas, words or data of others in your assessment, you must thoroughly and clearly acknowledge the source of this information by using the correct referencing style for your unit. Using others’ work without proper acknowledgement may be considered a form of intellectual dishonesty.
Participating honestly, respectfully, responsibly, and fairly in your university study ensures the CQUniversity qualification you earn will be valued as a true indication of your individual academic achievement and will continue to receive the respect and recognition it deserves.
As a student, you are responsible for reading and following CQUniversity’s policies, including the Student Academic Integrity Policy and Procedure. This policy sets out CQUniversity’s expectations of you to act with integrity, examples of academic integrity breaches to avoid, the processes used to address alleged breaches of academic integrity, and potential penalties.
What is a breach of academic integrity?
A breach of academic integrity includes but is not limited to plagiarism, self-plagiarism, collusion, cheating, contract cheating, and academic misconduct. The Student Academic Integrity Policy and Procedure defines what these terms mean and gives examples.
Why is academic integrity important?
A breach of academic integrity may result in one or more penalties, including suspension or even expulsion from the University. It can also have negative implications for student visas and future enrolment at CQUniversity or elsewhere. Students who engage in contract cheating also risk being blackmailed by contract cheating services.
Where can I get assistance?
For academic advice and guidance, the Academic Learning Centre (ALC) can support you in becoming confident in completing assessments with integrity and of high standard.
What can you do to act with integrity?
