A valid IQ test is based on the Bell Curve. Scores are reported as Standard Scores, which are based on a mean of 100 and a standard deviation of 15…meaning that 68% of the population has an IQ between 85 and 115. Any test that reports numbers correct is not an IQ test because numbers correct does not tell you how a person performed when compared to his peers. An IQ test is not an equal-interval test, meaning that a score of 100 is not exactly twice as good as a score of 50. The Wonderlic purports to be a test of problem solving ability, which is only one small avenue of IQ. It reports number correct, meaning that it is not norm-referenced and thus cannot be an IQ test. Of course, it does not purport to be an IQ test, so therefore, it is not falsely representing itself. As you said "is a general test of problem solving ability that many consider to be the best measure of intelligence." They are using a test of problem solving ability as an INDICATER of intelligence, when according to most experts it is only a piece of intelligence. They are not selling it as an IQ test. They are writing it so that those that don't know much about iq tests can take it that way- thats called marketing. But if you also notice those that do know about iq tests can also read it and they are still not falsely representing the product- thats called clever marketing.
Examples of IQ tests are Woodcock Johnson III, Standord-Binet V, Weschler Adult Intelligenct Scale, Kaufman Assessment Battery for Children-2nd Edition- All of which have to be given by trained professionals.
Now the rest about averages, cultural differences, and norming, I really dont feel like taking the time to explain it to Tide. There is too much venom in your posts. Get a book on Psychometrics.
If anyone elso has questions, of course I don't mind.
