Students who successfully complete this subject will be able to:

  1. Specify the objectives of an investigation in statistical terms
  2. Identify the level of measurement of a variable, appropriate sampling methods, and research design of a study
  3. Produce appropriate descriptions and visualisations of data distributions
  4. Estimate population parameters (proportions, means) using appropriate statistics and confidence intervals
  5. Select and conduct appropriate hypothesis tests for different population parameters (proportions, single sample means, difference of means for matched and independent samples)
  6. Describe the relationships between variables (correlations, crosstabs, relative risk and odds ratios) and test the significance of these relationships
  7. Interpret the outcomes of data analysis to write a concise report on findings.

This subject of study enables students to develop the capacity to undertake independent statistical investigations, including the assumptions and limitations of their application.  The subject will provide practical skills to allow students to meaningfully interpret the results of various hypothesis tests, as well as to understand probability distributions and sampling methods commonly applied when collecting data. 

Please note: assessment values are indicative only, details will be advised at the start of the subject. Students must get at least 40% in the exam to be eligible to pass the subject.
