Lesson details
Key learning points
- Data presented as a paired list can be represented as a scatter graph.
- Data presented in a table can be represented as a scatter graph.
- The independent variable is placed on the horizontal axis.
Keywords
Scatter graph - A visual representation for bivariate data. It can be useful when determining the nature of the relationship between the two variables.
Independent/Explanatory - An independent (explanatory) variable is a measure that is predicted to have an effect on another variable
Dependent/Response - A dependent (response) variable is a measure whose value is predicted to be affected by an explanatory variable
Bivariate data - Bivariate data has two variables, where each data point for one variable has a corresponding data point for the other variable.
Common misconception
Task B Q2 - Pupils may choose to go up in 100s on the vertical axis.
Highlight that all of their data points will be in the bottom half of the graph and suggest going up in 50s.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
