## Unit description of WACE Maths Applications Unit 4 Year 12 ATAR Course

WACE Maths Applications Unit 4 Year 12 ATAR Course has three topics:

- Time series analysis,
- Loans, investments and annuities, and
- Networks and decision mathematics.

‘Time series analysis’ continues students’ study of statistics by introducing them to the concepts and techniques of time series analysis. The content is to be taught within the framework of the statistical investigation process.

‘Loans investments and annuities’ aims to provide students with sufficient knowledge of financial mathematics to solve practical problems associated with taking out or refinancing a mortgage and making investments.

‘Networks and decision mathematics’ uses networks to model and aid decision making in practical situations. Classroom access to the technology necessary to support the graphical, computational and statistical aspects of this unit is assumed.
