Misleading Graphs


I was shown this corker of a graph recently. The scales there are wonderfully deceptive.

I love a good misleading graph. They’re really good for generating discussion, especially when you delve into the difference between a graph merely being wrongly created and a graph that’s been deliberately manipulated to be misleading, as this one has.

I’ve put together a selection of my favourite misleading graphs in this PDF.Obviously you don’t have to use them as worksheet, you can cut them out and use them however you want, or simply display them on the board to talk about.

If you use this resource, let me know how you get on in the comments. I’d love for this resource to generate discussion about how it generated discussion.

Edit : DataBlog Ammp3d (a blog that I will talk about here at some point) posted a funny correction to the Conservative graph on Twitter, which is well worth discussing.
