WebResiduals for data points. In the above graph, the vertical gap between a data point and the trendline is referred to as residual. The spot the data point is pinned determines whether the residual will be positive or negative. All points above the trendline show a positive residual and points below the trendline indicate a negative residual. WebPlot the residual values on the graph provided using data from the first and third columns of the table. The graph shows a near equal number of points above the line and below the line, and the graph shows no pattern. The regression equation appears to be a good fit.
