which of the following scatterplots do not show a clear relationship and would not have a trend line?
Answer
Explanation:
Step1: Analyze first scatter - plot
Examine the points in the first scatter - plot. The points seem to follow a somewhat upward - sloping pattern, indicating a positive relationship. A trend line could be approximated for these points.
Step2: Analyze second scatter - plot
Look at the points in the second scatter - plot. The points are randomly scattered across the graph. There is no discernible upward or downward pattern, nor any other clear relationship. So, a trend line cannot be reasonably drawn for this set of points.
Answer:
The second scatter - plot does not show a clear relationship and would not have a trend line.
