Answer:
- Graph B (according to the figure attached to the answer) best model the data in the scatter plot.
Step-by-step explanation:
- We know that a line of best fit also known as a trend line is the line that best represent the data points.
i.e. the points are closely related to the line.
- Also, the other properties of a trend line are--
The magnitude of the negative and positive residual values must be same.
( i.e. Not all point could lie above the line and not all points could lie below the line )
( In graph A most of the points lie below the line.
Hence, Graph A is not the correct answer.
In graph most of the points lie above the line.
Hence, Graph C could not be the best model.
In graph D most of the points lie above the line and hence it could not be the best model)
whereas in Graph B there are equal number of points above and below the line.
