Have a look at the file Heads by dragging it into Locus. This is a file which plots head size against height for members of my Year 7 class and their families. One of the girls included the data for her two dogs. See if you can pick out the dogs. This garbage data completely sewed up the argument as to whether or not there was a connection. When you've had a look at the original file, drag the Heads_NoDogs file on and see if you were right.
