The Best Fit Line Ruler takes the guess work out of determining the line that captures the most central points on a scatter graph. Simply lay the clear ruler over your graph of plotted points and the measuring grid will help make sure you get as many points as possible closest to the central groove. Then slide your pencil along that groove and voila – you have your best fit line!
