Textbook Incompetence

“A random sample of 50 pieces of plastic are being used 6mm these pieces of nylon rope are taken and the breaking strength (KN) is measured.” That, says Jason Richardson, a University of South Florida junior, is a quote from a textbook he bought for around $180, and he has no idea what it’s supposed to mean. Even the math in “The Joy of Statistics” is unreliable, he said: “We’re told CI equals CI divided by N, which wouldn’t make sense because you can’t divide CI by something to get CI.” Even better is publisher Kendall Hunt’s response when Richardson complained and asked for a refund: “I don’t think it’s fair that you unload 3 years of anger on my editor.” (AC/WFTS Tampa) ...If you really want to see math that doesn’t make sense, study the economics of higher education.
