Scatter Plot Statistics Example 3
Follow the full solution, then compare it with the other examples linked below.
Example 3
mediumA scatter plot shows the relationship between age of a car (years) and its resale value (\$). The points slope downward from left to right. Describe the association and explain what it means in context.
Solution
- 1 Step 1: Downward slope means negative association — as age increases, resale value decreases.
- 2 Step 2: In context: older cars tend to be worth less, which makes sense due to depreciation.
Answer
Negative association: as car age increases, resale value tends to decrease (depreciation).
Scatter plots not only show statistical patterns but also allow us to interpret real-world relationships between variables.
