Overview

Probability and Statistics in Year 9 is an important component of the Statistics and Probability strand for the NSW Mathematics K-10 syllabus. In this program, students are taught the concepts of theoretical probability and experimental probability, and how to represent the data gathered in Venn diagrams, tree diagrams, and two way tables. Other concepts that are covered include constructing and interpreting stem and leaf plots, frequency distribution tables and histograms, as well as calculating and comparing five number summaries for box and whisker plots.
