Scatter Graphs & Correlation

Describe simple mathematical relationships between two variables using scatter graphs, identify positive, negative, or no correlation, and use a line of best fit to make predictions

How to tell they’ve got it

Tick these off as you see them — no test required.

Plot bivariate data on a scatter graph and describe the type of correlation observed
Draw a line of best fit by eye and use it to estimate a value within the data range
Explain what positive, negative, and no correlation mean in the context of real data (e.g., temperature vs. ice-cream sales)

Try this together

If your child plotted a scatter graph — say, comparing hours of revision and test scores — could they draw a line of best fit, describe the pattern, and use it to make a prediction?

Builds on

Statistical Analysis Vocabularyages 9–11Describing correlation and using a scatter graph requires 'correlation', 'scatter graph', and 'line of best fit'

Comparing measurementsages 11–13Interpreting scatter graphs requires understanding averages and data distributions

Coordinates (age 11+)ages 11–12Scatter graphs require confident coordinate plotting in the first quadrant and beyond

Linear Function Graphsages 12–14Line of best fit connects to understanding linear relationships from y = mx + c

Curriculum alignment

Candidate matches to official curriculum codes — machine-suggested, unreviewed (v0.1).

This skill sits beyond Year 6 in the Australian Curriculum, so no F–6 code is matched. It also sits beyond the NSW K–6 syllabuses. It also sits beyond Level 6 in the Victorian Curriculum.
