Maths Unit: Investigating and Interpreting Data
The Investigating and Interpreting Data Unit Plan is a comprehensive teaching resource designed to help students develop essential data literacy skills. The unit guides students through collecting, organising, representing and analysing data, introducing concepts such as primary and secondary data, data variation and outliers. The resource provides a progressive learning structure, complete with real-world examples, worksheets, fast-finisher activities and links to digital resources such as quizzes and games.

Learning goals
- We are learning to interpret and compare the four types of data sets (ordinal, nominal, discrete, continuous) using comparative displays and determining the range, mode (frequency) and shape of data in graphs, dot plots and bar charts.
- We are learning to interpret secondary data (data collected by others) represented in digital media, books, scientific papers etc. and identify potentially misleading data representations.
- We are learning to pose questions, collect and interpret categorical or numerical data by observation or survey.
- We are learning to interpret and compare data displays, including side-by-side column graphs, tables and diagrams for two categories (e.g. age, height) and compare the usefulness of each display for data interpretation.
- We are learning to interpret secondary data (data collected by others) represented in digital media, books, scientific papers etc. and identify potentially misleading data representations.
