6. Representing data
Think about all the different was you know that data can be represented graphically and make a quick sketch on post-its of each one you think of.
Make sure you use a separate post-it for each diagram
It doesn’t have to be neat or accurate but it does need to be recognisable.
Pick one person to stick their diagrams in a row on the wall and write a label describing the diagram underneath.
