Unit description Unit description

This unit provides students with a comprehensive overview of multivariate data analysis and visualisation. Through hands-on experience with R and other tools, students will learn to manipulate, summarize, and visualise data with multiple variables. They will explore a range of multivariate graphical techniques, such as grouping, faceting, clustering, and time-dependent graphs, and will be introduced to modern methods for hypothesis testing, including MANOVA and multivariate regression. The unit will also cover the creation of interactive dashboards. Students will develop the ability to use statistical graphics to explore data, check statistical model assumptions, and effectively communicate results to diverse audiences. By the end of the unit, students will have a solid understanding of the differences between univariate and multivariate analysis, and will be equipped with valuable skills for working with complex data sets and creating informative dashboards.

Learning Outcomes

On successful completion of this unit, you will be able to:

  • ULO1: Demonstrate a comprehensive understanding of multivariate data analysis, including its limitations and applications, and the connection between multivariate and corresponding univariate techniques.
  • ULO2: Select and apply statistical tests to test hypotheses related to multivariate data and critically evaluate the reliability and validity of the statistical tests.
  • ULO3: Proficiently conduct MANOVA and multivariate regression models in real-world scenarios.
  • ULO4: Employ modern graphical techniques appropriately to reveal insights and patterns in multivariate data.
  • ULO5: Generate appropriate graphics using particular software packages or languages, and demonstrate the ability to adapt graphical techniques to other software
  • ULO6: Use statistical graphics to investigate and analyse data, check statistical model assumptions and effectively present the results of statistical investigations graphically to a range of audiences.

General Assessment Information

Requirements to pass this unit:

  • Achieve a total mark equal to or greater than 50%

ASSIGNMENT SUBMISSION: Assignment submission will be online through the iLearn page. Submit assignments online via the appropriate assignment link on the iLearn page.

  • Assignment submission is via iLearn. You should upload this as a single scanned PDF file.
  • It is your responsibility to make sure your assignment submission is legible.

You may submit as often as required before the due date/time. Please note that each submission will completely replace any previous submissions. It is in your interests to make frequent submissions of your partially completed work as insurance against technical or other problems near the submission deadline.

Late Assessment Submission Penalty

From 1 July 2022, Students enrolled in Session based units with written assessments will have the following university standard late penalty applied.

Unless a Special Consideration request has been submitted and approved, a 5% penalty (of the total possible mark) will be applied each day a written assessment is not submitted, up until the 7th day (including weekends). After the 7th day, a grade of '0' will be awarded even if the assessment is submitted. Submission time for all written assessments is set at 11:55 pm.

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

For any late submission of time-sensitive tasks, such as scheduled tests/exams, performance assessments/presentations, and/or scheduled practical assessments/labs, students need to apply for Special Consideration.

Assessments where Late Submissions will be accepted

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

  • Quiz - YES, Standard Late Penalty applies
  • Group Project - YES, Standard Late Penalty applies
  • Quantitative Data Analysis task - YES, Standard Late Penalty applies
  • Final Examination - NO, unless Special Consideration is Granted
