Unit description Unit description

This unit provides a comprehensive introduction to modern statistical principles and practices, specifically focusing on data analytical techniques. The primary objective is to develop a solid foundational understanding of the fundamental principles underlying statistical analysis. Throughout the unit, students will gain hands-on experience in data analysis using appropriate statistical software. The unit covers a range of essential topics, including the numerical and visual summarization of sample data, the basics of probability theory, and the concepts of discrete and continuous random variables. Furthermore, this unit covers sampling distributions and their fundamental properties. It also includes hypothesis testing for means, proportions, categorical data, and simple linear regression analysis. To fully benefit from this unit, a solid proficiency in mathematics is assumed, and it is specifically designed for students with a strong mathematical background.

To pass this unit you must:

  • Attempt all assessments, and
  • Achieve a total mark equal to or greater than 50%

Late Assessment Submission Penalty 

Unless a Special Consideration request has been submitted and approved, a 5% penalty (of the total possible mark of the task) will be applied for each day a written report or presentation assessment is not submitted, up until the 7th day (including weekends).

A 1-hour grace period will be provided to students who experience a technical concern.

For any late submission of time-sensitive tasks, such as scheduled tests and exams, students need to submit an application for Special Consideration.

In this unit, late submissions will be accepted as follows:

  • Web Quizzes: NO, unless Special Consideration is granted
  • Mid-Semester Test: NO, unless Special Consideration is granted
  • Final Examination: NO, unless Special Consideration is granted

Special Consideration

The Special Consideration Policy aims to support students who have been impacted by short-term circumstances or events that are serious, unavoidable and significantly disruptive and which may affect their performance in assessment. If you experience circumstances or events that affect your ability to complete the written assessments in this unit on time, please inform the convenor and submit a Special Consideration request through ask.mq.edu.au.

Delivery and Resources

Classes

Lectures (beginning in Week 1): There are two one-hour lectures each week.

Small-Group Teaching Activities (SGTAs) (beginning in Week 2): Students must register for the SGTA class.

Practicals (beginning in Week 2): Students must register for the Practicals class.

The timetable for classes can be found on the University website at: http://www.timetables.mq.edu.au.

Enrolment can be managed using eStudent at: https://students.mq.edu.au/support/technology/ systems/estudent.

Maths Background Quiz

This is a set of questions (pdf format) to allow students to assess whether they have sufficient mathematics in their background for STAT1371. Students are to attempt the quiz in their own time and mark it using the supplied solutions. Only students intending to do an Actuarial Studies degree have STAT1371 as a core unit. For all other students, you should do one of FOSE1015, STAT1170 or STAT1250 based on your degree requirement.

Calculators

Each student will need a small calculator, preferably one that does simple statistical calculations (it should have at least mean and standard deviation capability).  You should bring it to all SGTA classes.  A calculator will also be needed for the mid-session tests and the final examination.  You will not be permitted to use a programmable calculator or one with a full alpha character set in any examination.

Changes from Previous Offering

We value student feedback to be able to continually improve the way we offer our units. As such we encourage students to provide constructive feedback via student surveys, to the teaching staff directly, or via the FSE Student Experience & Feedback link on the iLearn page.

Student feedback from the previous offering of this unit was positive overall, with students pleased with the clarity around assessment requirements and the level of support from teaching staff.  However, there was a strong preference for two one-hour lectures instead of a two-hour lecture. As such, the delivery of the unit has changed to two one-hour lectures each week in this offering, and we will continue to strive to improve the level of support and the level of student engagement.
