Further to my post yesterday I’ve put the attached worksheet together for my students that didn’t get Q2 on the Edexcel March 2013 non calculator paper (which we used as an internal test) correct, but will be equally useful for anyone that is teaching scatter graphs.
I’m going to use it as part of my “mastery” lessons with my year 10s using their test analysis whereby they work through these style of worksheets before moving on to the next topic that they need to improve on.
