Follow the full solution, then compare it with the other examples linked below.
Example 4
mediumA scatter plot of practice hours and free-throw accuracy has points clustered tightly around an upward-sloping line. Describe the direction and strength of the association.
Solution
- 1 Step 1: An upward trend means the association is positive because larger x-values go with larger y-values.
- 2 Step 2: Because the points are tightly clustered around a line, the association is strong.
Answer
The scatter plot shows a strong positive association.
Scatter plots are interpreted by direction, form, and strength. Tight clustering around a line indicates a strong relationship, while the upward slope shows it is positive.
