Question

four students created scatter plots on a graph.
graph 1\tgraph 2\tgraph 3\tgraph 4
images of four scatter plots
determine which student created each graph by the descriptions below.
kevin’s graph shows a weak, linear association.\tchoose
barry’s graph shows weak, non - linear association.\tchoose
michael’s graph shows no association.\tchoose
julie’s graph shows the strongest association.\tchoose

Explanation:

To solve this, we analyze the scatter plots based on association types:

1. Annie’s graph (weak, linear association)

A weak linear association has points loosely following a line. Graph 4’s points show a slight upward trend but are spread out, so Annie → Graph 4.

2. Henry’s graph (weak, non - linear association)

A weak non - linear association has points with no clear linear trend. Graph 1’s points form a curve (not a straight line) and are spread, so Henry → Graph 1.

3. Michael’s graph (no association)

No association means points are randomly scattered. Graph 2’s points have no clear trend, so Michael → Graph 2.

4. Julie’s graph (strong, negative association)

A strong negative association has points closely following a downward - sloping line. Graph 3’s points are tightly clustered along a negative slope, so Julie → Graph 3.

Answer:

s:

• Annie: Graph 4
• Henry: Graph 1
• Michael: Graph 2
• Julie: Graph 3
