24. Scatter Graphs
Scatter graphs are used to show whether there is a relationship between two sets of data. The relationship between the data can be described as either:
1. A positive correlation. As one quantity increases so does the other.
2. A negative correlation. As one quantity increases the other decreases.
3. No correlation. Both quantities vary with no clear relationship.
