Correlation
I can recognise relationships between bivariate data represented on a scatter graph.
Lesson details
Key learning points
- The distribution of data points may suggest positive correlation.
- The distribution of data points may suggest negative correlation.
- The distribution of data points may suggest no correlation.
- Correlation does not imply causation
Common misconception
Correlation always means that one of the variables is affecting the other variable.
Correlation only suggests variables may be related somehow. Show examples where variables correlate because they both depend on population.
Keywords
Correlation - Correlation describes the extent to which the relationship is close to a linear relationship.
In the first learning cycle, ask students to consider other things in a town/city that may change depending on the size of the population. Imagine whether these things might have a positive or negative correlation and why.
