Prior Knowledge
- Data (Stage 2)
Collect categorical and discrete numerical data by observation or survey
- Pose and refine questions to construct a survey to obtain categorical or discrete numerical data about a matter of interest
- Collect ordinal or nominal categorical data, and discrete numerical data through observation or by conducting surveys
Choose and use appropriate tables and graphs
- Tabulate collected data with and without the use of digital technologies such as spreadsheets
- Recognise which types of data display are appropriate to represent data (Statistical reasoning)
- Determine an appropriate scale (horizontal and vertical) to represent the data
- Construct column graphs using a many-to-one scale, with and without the use of digital technologies
- Draw an accurate timeline using an appropriate scale
Describe and interpret different datasets in context
- Interpret line graphs using the scales on the axes
- Describe and interpret data presented in tables, column graphs and line graphs
- Determine the total number of data values represented in column graphs
