I collect bad graphs.
I used to keep them as a PowerPoint, but I thought I’d bring them together here as a slideshow. I did promise to do this a month ago. Sorry to @VVMinkov on Twitter.
Usually I present the graphs. Ask students to think for themselves for 30 seconds. Then talk to their partner to 1 minute.
I might ask : ‘Why is this graph bad? Do you think it is deliberately bad? If so, are the creators of the graph trying to tell a story? If not, what mistakes have they made?’
I will try and update this slideshow when people send me more bad graphs.
