Question
For each scatter plot , Identify the association between the data. If there is no association ,state so.
Hint:
If the scatter plots are close to the trend line, it’s a strong association. If they are far from the trend line, it’s a weak association.
The correct answer is: We are asked to identify the association between the data. State the reason, If there is no association.
We are asked to identify the association between the data. State the reason, If there is no association.
Step 1 of 3:
The trend line of part (a) can be drawn as:
Here, the plots are close to the trend line.
Hence, it’s a strong association.
Step 2 of 3:
The trend line of part (b) cannot be drawn, since the points on the scatter plot forms a curve.
Hence, it is a nonlinear association.
Step 3 of 3:
Here, the scatter plots are far from the trend line. Hence, they are weak association.
Here, the plots are close to the trend line.
Hence, it’s a strong association.
Step 2 of 3:
The trend line of part (b) cannot be drawn, since the points on the scatter plot forms a curve.
Hence, it is a nonlinear association.
Step 3 of 3:
Here, the scatter plots are far from the trend line. Hence, they are weak association.
If the plots are clustered together around the trend line, it forms a strong association. Whereas, if the points are away from the trend line, it forms a weak association.

Does the scatter plot show a linear or non linear association ?
Using scatter plots to distinguish between linear and nonlinear relationships
Step 1: Examine the scatter plot. What happens when you move to the right in general? Do the points increase in general? Get Lower? Is there no overarching pattern?
Step 2: Interpret your observations. Looking from left to right,
• If the points tend to rise in general, following a reasonably straight line, then the relationship is linear.
• The points tend to get lower generally, following a relatively straight path, which is a linear relationship.
• If the points tend to rise in general, but the path is very curved, the relationship is nonlinear.
• The points tend to get lower in general, but if the path is very curved, it is a nonlinear relationship.
• If the points do not consistently move up or down, the relationship is nonlinear.

Georgia and her classmates are measuring their height and arm span. They record their data in the table.
How can they determine what relationship , if any exists between the two sets of measurements.
The scatter plot will be enough to show the relation. The line graph would help us the study the data in depth.
