Data Handling

Central idea:

Data allows us to summarise what we know about the world and make inferences about what we do not know.

Key Concepts:

Function, Causation and Reflection

Lines of inquiry:

• The methods used to collect, record and organise data
• The reasons for collecting data.
• How we know what the data is describing.

Teacher questions:

• How do we collect, record and organise data? (function)
• Why do we collect data? (causation)
• How do we interpret the data? (reflection)

Learning outcomes:

• LO1. Design a survey and systematically collect, record, organise and display the data in bar graphs and line graphs.
• P – as above;
• HP – find the answer to a question(for example Do we really shrink during the day? What happens to the class temperature during the day?) through a statistical analysis using the above skills and interpretation
