Under certain circumstances, least squares lines seem to be wrongly labelled.  It appears to have something to do with the alphabetical order of categories in a categorical variable, and their display on the graph. It does not always happen: notice that the variable Type appears to work correctly, and also, that the alphabetical order is reversed. This was discovered on a different data set, but wanted to see if it could be reproduced with “official” CODAP data.
