Investigating and Interpreting Data - Presentation
The Investigating and Interpreting Data Presentation is an engaging and structured PowerPoint designed to introduce students to primary and secondary data collection. It explains key statistical concepts such as variation, outliers and trends while encouraging students to analyse real-world data and apply critical thinking to problem-solving scenarios. With interactive questions and real-life examples, this resource provides an excellent foundation for developing data literacy skills.
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.

Differentiation
Modifications
• Provide simpler data sets and visual representations for younger students.
• Use sentence starters and guided discussion prompts to help students articulate their findings.
• Extend for older students by introducing comparative analysis of multiple data sets.
Extensions
• Assign students a data investigation project where they collect and interpret their own primary data.
• Have students create their own "Did You Know?" fact sheets using secondary data.
• Encourage fast finishers to analyse outliers and hypothesise their causes.
