Understanding Statistics

Mark Twain once said, "There are lies, damn lies, and statistics." The implication is that there is a continuum from the truth through lies to extreme lies, with statistics even more extreme on this continuum. 

We would be lying if we said that selective use of statistics has never been used by unscrupulous people to mislead. But the more you know about statistics, the less likely it is that you can be misled by either the deliberately unscrupulous or the naively ill informed. That's right, statistics can be as misleading in the hands of someone with a limited understanding of statistics as in the hands of a true psychopath trying to sell you a building lot in the middle of a swamp.
