I caught what you are talking about. The guy then said that he refigured all the figures - and only those two (I think it was two) were wrong. What did you get out of that? If he had refigured all the figures - would more than that have come out wrong - or could the median and mean been the same on all those other figures? Do you understand what I'm getting at?
I wasn't following close enough to get anything out of it. What troubles me is that he didn't understand the difference in a basic math concept.
Either he was being deceitful or inadequately trained in math. In that I cannot fathom he doesn't know the difference my guess would be he was being deceitful because he realized his criticism wasn't warranted and didn't want to admit.
