I always felt that the quote indicated that statistics are easily used to mislead with credibility. When I homeschooled my sons, I gave them a choice between the algebra/geometry/calc track and a statistics track. They chose statistics. An interesting book we included in our studies was "How to lie with statistics". (FWIW: I think there was a later book called something like "
How to lie with charts and graphs".)
My point was not that statistics are lies but just that the statement "Graphs don't lie" isn't some kind of unquestionable grand truth.
