Unit description
This unit deals with the gathering and analysis of data. Students are given the foundations of survey design with some discussion of quota sampling; question construction; common ambiguities and unintended biases; probability sampling; simple random sampling; stratified sampling; ratio and regression estimators; systematic sampling; and cluster sampling. The other component of the unit is a discussion of designed experiments and covers the following topics: the completely randomised design; randomised blocks; random effects models; and analysis of covariance.

Assessment Tasks
| Name | Weighting | Hurdle | Due |
|---|---|---|---|
| Tutorial participation | 10% | No | Weeks 2-13 |
| Assignments | 30% | No | Tuesday (Week 6, 8 & 12) |
| Examination | 60% | No | University Examination Period |
Tutorial participation
Due: Weeks 2-13
Weighting: 10%
Each week a set of tutorial exercises is made available on iLearn for students to practice. Students are required to participate a 1-hour tutorial class per week from Week 2, contributing to the class discussion with fellow students and the tutor.
On successful completion you will be able to:
- understand commonly used experimental designs and be able to apply appropriate statistical method(s) for the analysis of data arising from each design
- understand basic survey sampling, be familiar with concepts such as sampling bias, sampling and non-sampling errors, and know the basics of questionnaire design and question construction
- understand commonly used survey designs and sampling methods, and be able to use appropriate statistical technique(s) to estimate population parameters based on a sample from each design
Assignments
Due: Tuesday (Week 6, 8 & 12)
Weighting: 30%
Three assignments (10% each) are set for students to complete independently, applying the knowledge gained from lectures, tutorials and their own reading, with and/or without using the statistical software, Minitab. They will be made available on iLearn.
Each of the three assignments should be submitted electronically on the unit iLearn by its due date and time, which will be included in the assignment. Students must keep a soft or hard copy of any assignment submitted. In the event of an assignments being misplaced, a replacement of it will be requested.
In the case of a late submission for the assessments, if no special consideration has been granted, 10% of the earned mark will be deducted for each 24 hour period of part thereof that the submission is late (for example, 25 hours late in submission - 20% penalty), up to a maximum of 50%. After 5 days, counted including weekends and public holidays, a mark of 0% will be awarded. NOTE: It is not the intention of this late penalty policy to cause a student to fail the unit when they have submitted their assignment no more than 5 days after the due date and they would have otherwise passed. In this case, if deductions for late assignments result in the final unit mark for a student being less than 50, when otherwise it would have been 50 or greater, the student's final mark will be exactly 50.
On successful completion you will be able to:
- understand commonly used experimental designs and be able to apply appropriate statistical method(s) for the analysis of data arising from each design
- understand basic survey sampling, be familiar with concepts such as sampling bias, sampling and non-sampling errors, and know the basics of questionnaire design and question construction
- understand commonly used survey designs and sampling methods, and be able to use appropriate statistical technique(s) to estimate population parameters based on a sample from each design
- have generally improved problem solving ability
- have improved the ability to use computing software (Minitab) in solving practical problems
Examination
Due: University Examination Period
Weighting: 60%
There will be a three-hour written examination that will be timetabled within the official University Examination Timetable. The University Examination Timetable will be available in draft form approximately eight weeks before the commencement of the the University examinations and in final form approximately four weeks before the commencement of the examinations at: http://students.mq.edu.au/student_admin/exams/
The only excuse for not sitting an examination at the designated time is because of documented illness or unavoidable disruption. In these special circumstances you may apply for special consideration via ask.mq.edu.au.
If you receive special consideration for the final exam, a supplementary exam will be scheduled in the interval between the regular exam period and the start of the next session. By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. You can check the supplementary exam information page on FSE101 in iLearn (bit.ly/FSESupp) for dates, and approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.
On successful completion you will be able to:
- understand commonly used experimental designs and be able to apply appropriate statistical method(s) for the analysis of data arising from each design
- understand basic survey sampling, be familiar with concepts such as sampling bias, sampling and non-sampling errors, and know the basics of questionnaire design and question construction
- understand commonly used survey designs and sampling methods, and be able to use appropriate statistical technique(s) to estimate population parameters based on a sample from each design
- have generally improved problem solving ability
Delivery and Resources
Classes

Technology Used and Required
Software: Minitab is used in this unit. Information about Minitab can be found on its web site at http://www.minitab.com. This software is provided for free to Macquarie students, and can be downloaded from the student portal at http://students.mq.edu.au/home/ for home use. Students can also use Minitab online via iLab (https://wiki.mq.edu.au/display/iLab/About). Remember that any work or results produced via iLab in all computing labs on the University campus must be saved onto iLab desktop and then emailed to yourself.
Calculator: An electronic calculator is required throughout this unit. Only calculators with no text retrieval capacity are permitted to be used in the examination.
Unit Web Page and iLearn access: Enrolment in STAT373 should automatically make the STAT373 iLearn site available to you from the start of semester. To access it, log in at https://ilearn.mq.edu.au/login/MQ/ and select STAT373 from your list of iLearn units. If STAT373 doesn’t appear, though, and you enrolled in the unit more than 24 hours ago, please contact the Unit Convenor immediately. Note that you should visit this web site regularly for course materials including lecture slides, lecture recordings, tutorials and assignments, and also possible announcements placed by the Lecturer.
The Discussion Forum on the unit iLearn can be used for online discussion with other students enrolled in STAT373 on any problems or topics related to the unit. The lecturer will visit the Forum from time to time.
Learning and Teaching activities
Lectures: Lectures begin in Week 1. Students are required to attend a 3-hour lecture each week. Topic(s) for each week are set in the Unit Schedule in this unit guide. Students are encouraged to read the relevant chapter(s) recommended before coming to the lecture.
An iLecture will be recorded for each lecture when possible and made available on the unit iLearn (under echo360) soon after the lecture is completed.
Tutorials and Tutorial exercises: Students are required to attend a 1-hour tutorial per week from Week 2. A set of tutorial exercises will be made available each week for students to practice, which is usually presented on the last slide(s) of each lecture.Students are encouraged to complete relevant tutorial exercises before coming to their tutorial class where the solution to the tutorial exercises is discussed. The tutorial solution will be also made available on iLearn soon after the class.
Assignments: Three assignments are set in this unit for students to complete independently. To assist with further learning, solutions to the assignments (when possible) will be made available later on iLearn.
