Activity designed to give further practice (Maths Mastery) of line of best fit on scatter graphs after initial teaching and practice. Particularly to reinforce what happens when there is no correlation.
Twenty seven slides on the PowerPoint. Each slide shows a scatter graph which either has correlation or hasn't. If it has correlation then a line of best fit can be drawn and the degree or strength of the correlation can be suggested (Note that at this level it is a subjective judgement so answers may vary).
The graphs are simply ones found using a internet image search, but I've done the work for you to save you the time.
There is a matching PowerPoint which has my suggested solutions on.
I rearranged the order of the slides on the PowerPoint on the Print version (attached) and then printed out pages 1-6, then 7-12, and so on so that six graphs were on each sheet of A4 (using the handout feature of PowerPoint). This means that you now have four worksheets which are all slightly different so that every student on your tables of four has a different set of questions - hence less copying. The answers to the four sheets I made are attached as a PDF.
This is a good activity which did meet the objective of reinforcing the LOBF skills.
