Barbara, "There are three kinds of lies, lies, damned lies and ststistics." DARRELL HUFF, author of "How to Lie with Statistics"(1954) His primer has been read by over half a million readers. His text shows how to deceive people with SAMPLING (random or stratified) in the use of AVERAGES(mean, median,or modal) ERRORS(probability, standard or unintentional) misuse of GRAPHS, INDEXES, and other TOOLS of Democratic persuasion. His text was used in my freshman statstics class. I have used it for 53 years. Anthony and A155MM' s critique's is valid.
