To determine which scatterplot shows a linear association, we can analyze the sets of data provided to identify any trends or patterns.
Here is the breakdown of the four datasets:
1. **First Data Set:**
- Points: (5.0, 12.0), (4.6, 8.5), (8.5, 6.0), (7.8, 10.0), (6.8, 12.0), (5.3, 10.0), (7.0, 12.0), (7.2, 10.0)
- This dataset has a general downward trend with some clusters, indicating a possible non-linear association.
2. **Second Data Set:**
- Points: (5.0, 3.7), (4.6, 2.7), (8.5, 6.5), (7.8, 2.0), (6.4, 5.6), (6.8, 3.0), (7.0, 7.8), (7.2, 6.7)
- This dataset does not show a clear pattern and appears scattered without an apparent linear trend.
3. **Third Data Set:**
- Points: (5.0, 9.5), (4.6, 9.0), (5.9, 11.0), (7.8, 13.0), (6.4, 11.5), (6.8, 12.0), (5.3, 10.0), (7.2, 12.5)
- This dataset shows a more consistent upward trend, indicating a strong linear association.
4. **Fourth Data Set:**
- Points: (5.0, 12.0), (4.6, 9.0), (8.5, 15.0), (5.9, 11.0), (7.8, 13.0), (5.3, 8.0), (7.0, 14.5), (7.2, 10.0)
- This dataset shows some upward and downward trends but lacks a clear pattern indicating linearity, since the points are quite scattered.
Given this analysis, the **third dataset** appears to show the best linear association. You would see a clear upward trend if you plotted these points on a scatterplot.
Here is the breakdown of the four datasets:
1. **First Data Set:**
- Points: (5.0, 12.0), (4.6, 8.5), (8.5, 6.0), (7.8, 10.0), (6.8, 12.0), (5.3, 10.0), (7.0, 12.0), (7.2, 10.0)
- This dataset has a general downward trend with some clusters, indicating a possible non-linear association.
2. **Second Data Set:**
- Points: (5.0, 3.7), (4.6, 2.7), (8.5, 6.5), (7.8, 2.0), (6.4, 5.6), (6.8, 3.0), (7.0, 7.8), (7.2, 6.7)
- This dataset does not show a clear pattern and appears scattered without an apparent linear trend.
3. **Third Data Set:**
- Points: (5.0, 9.5), (4.6, 9.0), (5.9, 11.0), (7.8, 13.0), (6.4, 11.5), (6.8, 12.0), (5.3, 10.0), (7.2, 12.5)
- This dataset shows a more consistent upward trend, indicating a strong linear association.
4. **Fourth Data Set:**
- Points: (5.0, 12.0), (4.6, 9.0), (8.5, 15.0), (5.9, 11.0), (7.8, 13.0), (5.3, 8.0), (7.0, 14.5), (7.2, 10.0)
- This dataset shows some upward and downward trends but lacks a clear pattern indicating linearity, since the points are quite scattered.
Given this analysis, the **third dataset** appears to show the best linear association. You would see a clear upward trend if you plotted these points on a scatterplot.
