# SACE Stage 2 General Mathematics – Statistical Models

3.1 Bivariate Statistics

3.2 The Normal Distribution

The linear and exponential growth behaviours studied in Linear and exponential functions and their graphs in Stage 1 General Mathematics are observed in bivariate data. Using electronic technology and statistical tools such as scatter plots and regression to analyse such data, students find algebraic models and use them for predictive purposes.

The normal distribution is an important mathematical model for predicting many social, industrial, and scientific contexts. Students investigate the characteristics and nature of the normal distribution through data simulation and graphical representation. They use this model to solve problems and make predictions in various contexts where data is expected to be approximately normally distributed.

Students use electronic technology to support calculations and presentation of their work throughout this topic.
