Maths Unit: Understanding Data
In this unit, students develop their understanding of what data is, where it comes from, and how they can interpret and present that data in tables and graphs.

Learning goals
- We are learning to pose questions, collect and interpret categorical or numerical data by observation or survey.
- We are learning to pose questions and collect categorical or numerical data by observation or survey.
- We are learning to acquire data and construct displays including column graphs, dot plots and tables appropriate for the type of data, determining the highest frequency (mode) of the data set.
- We are learning to construct displays, including column graphs, dot plots and tables, appropriate for the type of data.
- We are learning to interpret the data in line graphs representing change over time and draw conclusions.
- We are learning to describe and interpret different data sets.
