which scatter plot shows a trend line that best models the data?
Answer
Explanation:
Step1: Understand trend - line concept
A good trend - line in a scatter - plot should be as close as possible to most of the data points.
Step2: Analyze each option
In the first plot, the points are relatively close to the line. In the second plot, some points are far from the line. In the third plot, the points are also relatively close to the line, but the first plot seems to have points more evenly distributed around the line.
Answer:
The first scatter - plot (the one with points most evenly distributed around the line) shows a trend line that best models the data.
