Lesson on 5th March: Scatter Diagrams
Today we looked a bit at Scatter Diagrams. These are useful if you want to compare two things (or variables). We looked at three kinds of correlation (matching):
- Positive correlation - one variable increases as the other variable increases
- Negative correlation - one variable increases as the other variable decreases
- No correlation - one variable makes no difference to the other
Details of what we did are here.
There was no homework.
