I am glad it was noted. I don't really have time to read this (edit: and the comment by jacobolus saves me the effort). I have good empathy and social skills and innate math ability. My ex husband and our oldest son both suck at all three of those.
I think it is entirely fair to say that some oddball subgroup is skewing the results. It is no different from discussing mean, median and mode in real estate data.
Ever heard of the book "How to lie with statistics"?
