Course aims / learning outcomes

This course has two main parts:

  1. Using the Statistical Enquiry Cycle to investigate various types of relationships in datasets.
  2. Solving problems by calculating theoretical probabilities and using probability models.


Assessment statement

  • This course is roughly half internally, half externally assessed.
  • There are 20 credits on offer in the course.
  • It is University Entrance approved and also may be combined with some Calculus standards to create a Mathematics approved subject.
  • 12 of the credits come from Internal assessments.
  • 8 credits come from external exams.



  • In the internal all work must be completed in class, in a google doc shared with the Learning Advisor.


Appeal Procedures

  • Students have the right to appeal the mark they have been awarded. If a student wishes to appeal a grade, they should initially talk to the subject learning advisor about the marking process immediately after the marked assessment task is shown to them. If still dissatisfied the student should make an appointment and discuss grades with the Principal’s Nominee who will check that the correct procedures have been followed as outlined in the school and subject policies taking into account any special circumstances.
