Best Fit Line Rulers in IoP partnership

The Institute of Physics have partnered with BFLR to send all their affiliated schools a free IoP branded Best Fit Line Ruler. Read all about it in the December 2009 issue of Classroom Physics.

The BestFitLineRuler – BFLR -  makes locating and drawing the line of best fit on a line graph easy.

Just lay the clear ruler over your graph, once data points have been plotted, and the grid on the BFLR will help you to make sure you get as many points as possible as close as possible to the central slot. Then slide your pencil along the groove and there’s your best fit line.

With centimetre and millimetre markings along the edges, it acts as a traditional ruler too.

The simple innovation behind Best Fit Line Rulers has proved a big hit with teachers and pupils alike.  The north-east Science Learning Centre and the Institute of Physics have both made bulk orders, alongside many schools across the country.

“We reckon they’ll definitely help for GCSE,” said Andy Guest, Head of Maths at St Bede’s School in Lanchester, County Durham.
