Comparing and contrasting: shape, skewness, location and spread (1 Viewer)

[DancingAnz]

You know what i'm talking about... Interpreting sets of data topic... These questions get me every time! I thought I picked general maths to avoid writing sentences!
I don't know why but I just find it really hard to find similarities and differences between graphs, and when I do, I NEVER get full marks :/

Any tips, tricks of the trade??
