## Syllabus

PURPOSE
To teach student concepts and principles related to the application of statistical inference to real world data analysis problems.

LEARNING OUTCOMES

• Demonstrate an understanding of the fundamentals of estimation theory, with particular reference to: methods of point estimation, properties of estimators, and interval estimation; and understand and be able to implement mainstream statistical theory and methods for estimating parameters of an unknown population.
• Demonstrate an understanding of the fundamentals of Hypothesis Testing, with particular reference to: problems of hypothesis testing, testing simple hypotheses, statistical tests for means, variances and proportions, and statistical tests for comparing populations; and understand and be able to implement mainstream statistical theory and methods for testing hypotheses on parameters of an unknown population.
• Be capable of analytic thought and also of bringing together concepts, theory and methods from different areas of learning in order to solve problems; apply the appropriate statistical methods and statistical software to analyse data and interpret the results.
• Demonstrate the use of statistical principles and concepts, and the integration of knowledge from other disciplines, across real-world contexts.
