## 2.4 Scatterplots and Association between Numerical Variables

### Scatterplots

**Scatterplots**are used to visualise data with explanatory and response variables.- They consist of an x-y axis with each datapoint represented as a dot above its x-value and to the right of its y-value.
- Scatterplots can be used to see relationships between variables. These relationships can be described in terms of
**form, direction and strength**.
