Chapter 4: Much Ado about Practically Nothing
This chapter talks about two children and how they have taken an IQ test and that one of the children scored a higher score than the other and was therefore superior to that child. He then goes into a little rant about how IQ test don't really measure what they say they are going to measure and in fact he says that a mental test of any variety is one of the prime voodoo fetishes of our time. After he talks about the voodoo testing he talks more about the test scores that the two children got and you find out that one got a 101 and the other got a 98 and you also learn that the average is a 100.
So after you find out the scores and what not he goes and talks about how you need to keep in mind the plus-or-minus or a certain score or scores especially if they don't say what the range is. He then goes and gives some examples about corn fields and how you would have to inspect almost everyone to find the best crop between the two different crops and he gave an example of a magazine survey and how it could have been incorrect because the samples were only of a few hundred people and if a few put the wrong answer it could have drastic results. And he finally closes with an example of a cigarette company and a good quote, "a difference is a difference only if it makes a difference."
