Heh! Better than "After extensive analysis using multiple regression analysis and a liberal sprinkling of chicken entrails, the study concludes that the prehistoric carvings studied are exclusively and extensively found on the surface of rocks." Statistics do my head in at the best of times :)

I would be interested to see how the sites relate to flint scatters, particularly microlithic scatters. It would be interesting to see if there's any statistical evidence that sheds light on the idea of mesolithic cups.
