## Unit description of WACE Maths Applications Unit 3 Year 12 ATAR Course

WACE Maths Applications Unit 3 Year 12 ATAR Course has three topics:

• Bivariate data analysis,
• Growth and decay in sequences, and
• Graphs and networks.

Bivariate data analysis introduces students to some methods for identifying, analysing and describing associations between pairs of variables, including the use of the least-squares method as a tool for modelling and analysing linear associations. The content is to be taught within the framework of the statistical investigation process.

Growth and decay in sequences employs recursion to generate sequences that can be used to model and investigate patterns of growth and decay in discrete situations. These sequences find application in a wide range of practical situations, including modelling the growth of a compound interest investment, the growth of a bacterial population, or the decrease in the value of a car over time. Sequences are also essential to understanding the patterns of growth and decay in loans and investments that are studied in detail in Unit 4.

Graphs and networks introduces students to the language of graphs and the ways in which graphs, represented as a collection of points and interconnecting lines, can be used to model and analyse everyday situations, such as a rail or social network.

Classroom access to technology to support the graphical and computational aspects of these topics is assumed.

## Learning outcomes of WACE Maths Applications Unit 3 Year 12 ATAR Course

By the end of this unit, students:

• understand the concepts and techniques in bivariate data analysis, growth and decay in sequences and graphs and networks
• apply reasoning skills and solve practical problems in bivariate data analysis, growth and decay in sequences and graphs and networks
• implement the statistical investigation process in contexts requiring the analysis of bivariate data
• communicate their arguments and strategies, when solving mathematical and statistical problems, using appropriate mathematical or statistical language
• interpret mathematical and statistical information and ascertain the reasonableness of their solutions to problems and their answers to statistical questions
• choose and use technology appropriately and efficiently.
