In reply to jaap karman.

I will pass on your concerns to the education division.

My personal response is that I am not disturbed if course notes include the "mean is greater than the median" statement. It is true in 99% of the data that arises in practice. As Hipple points out, 14/18 standard textbooks mention this rule-of-thumb, some without qualification. The SAS course notes are not a textbook; they are intended to give students the main ideas and basic concepts. It also doesn't bother me if they say "equal" instead of "equal in probability almost everywhere" or if they say "the statistic is normally distributed" when a more correct statement would be "asymptotically normal for large samples."

I am sure that a mathematical statistician who reads my blog would find dozens of phrases that are technically incorrect as stated, but nevertheless serve as useful instructional statements.
