Course code

Qualifications are made up of courses. Some universities call these papers. Each course is numbered using six digits.



The fourth number of the course code shows the level of the course. For example, in course 219206, the fourth number is a 2, so it is a 200-level course (usually studied in the second year of full-time study).



Each course is worth a number of credits. You combine courses (credits) to meet the total number of credits needed for your qualification.

Learning outcomes

What you will learn. Knowledge, skills and attitudes you’ll be able to show as a result of successfully finishing this course.

  • 1 Use a statistical package to summarise data. Choose graphical and numerical summaries of a batch of values and use them to answer questions about variability and relationships in the data.
  • 2 Critically examine data collected by others and the conclusions that they draw.
  • 3 Collect data with surveys and experiments to help answer real-life questions and effectively present the information extracted from data to others.
  • 4 Use distributions and sampling to model variability in data.
  • 5 Use hypothesis tests to assess whether there are differences between groups or relationships between variables and estimate population characteristics with confidence intervals.

Learning outcomes can change before the start of the semester you are studying the course in.
