NettetA residual plot is a type of scatter plot that is used to determine whether a model is a good fit for the data. The horizontal axis of a residual plot represents the independent variable while the vertical axis represents the residual values.

A high residual indicates that the best fit line does not do a good job of modeling the data. Use the line of best fit to help you to describe the data correlation.

NettetHere's a process you might try. Find the point that is the closest to one corner. Then, find the point that is closest to the opposite corner. Connect those two points. Then, look at the line you draw and compare the rest of the points to it. If there are more points above the line than below it, then you might need to move the line up some. http://www.shodor.org/interactivate/discussions/UsingResiduals/
