This is a revolutionary new stationery instrument. It has all the uses of a traditional ruler, but can also help you to draw the best fit line on a scatter graph much more accurately and easily than you can with a traditional ruler. With the grid pattern, you can be really sure that you have the points equally spaced on either side of your best fit line, and as close to it as possible all the way along. Plus it has centimetre and millimetre markings so you still get all the functions of an ordinary ruler!
Use the BFLR to draw your graph and plot the points as normal, then use the grid to locate the best position for the best fit line, as indicated by the central slot in the middle of the ruler. Slide your pencil along this central slot to produce a crisp and accurate best fit line.
