You also should not see large clusters of adjacent points that are all above or all below the Y=0 line. If the assumptions of simple linear regression have been met, the residuals will be randomly scattered above and below the line at Y=0. ![]() You can treat the residuals table like any other table, and do additional analyses or make additional graphs. ![]() When Prism creates the table of residuals, it also automatically makes a new graph containing the residuals and nothing else. A residual with a positive value means that the point is above the line a residual with a negative value means the point is below the line. The X values in the residual table are identical to the X values you entered. If you check an option on the simple linear regression dialog, Prism will create a results table with residuals, which are the vertical distances of each point from the regression line. You can add lines to a graph or remove lines from a graph on the 'Data sets on graph' tab of the Format Graph dialog. ![]() If you need to create additional graphs, or change which line is plotted on which graph, keep in mind that the line generated by linear regression is seen by Prism as a data set. ![]() When Prism performs simple linear regression, it automatically superimposes the line on the graph. ![]()
