Scatter graphs and types of correlation
MA32-09
This lesson is coming soon.
In this lesson
Plot a scatter graph of bivariate data and name the type and strength of correlation shown using the required vocabulary.
What it covers
- Plot points on a scatter graph from bivariate (two-variable) data
- Name the type of correlation shown (positive, negative, none/zero) using the word 'correlation'
- Name the strength of correlation where required (weak/strong)
Key words
For: AQA GCSE 8300, Edexcel GCSE 1MA1, Eduqas GCSE C300, OCR GCSE J560, Cambridge IGCSE 0580
On the specification

For teachers
This GCSE Maths lesson teaches scatter graphs and types of correlation. By the end, students should be able to plot a scatter graph of bivariate data and name the type and strength of correlation shown using the required vocabulary. It works through two worked examples and the mistakes examiners report.
