Question

How do i match the Scatter Plots and given line are models to the graph of the residuels?

Answer 1

Answers:

First, scatter plot --> first residual graph

2nd scatter plot --> 2nd residual graph

3rd scatter plot --> 3rd residual graph

Step-by-step explanation:

The residuals are calculated as the difference between every dot (observed value) and the line (predicted value)

So, for the first graph we see that the dots are first above the line, then below the line, and then above the line again. So the difference will be positive, then negative, and then positive. It means that the graph of the residuals is the first one.

For the second graph, we have the dots first below the line and then above the line. So, the difference will be negative and then positive. Then, It matches with the second residual graph

Finally, the third graph has the dots above the line and then below the line, so the difference will be first positive and then negative and this graph will match with the third residual graph.

So, the matches are:
