The concepts of reliability and validity are very important whenit comes to the testing of intellectual abilities. When tests aregiven such importance (in terms of how we look at and use thenumbers), they must be carefully constructed to be as accurate aspossible. Could a test of intelligence be reliable, but not valid?How? Could some other measure (assessing something other thanintelligence) be valid, but NOT reliable? Why or why not? Giveexamples.
Of what practical use are intelligence tests? Does it matterwhat someone's \"IQ\" is? Why or why not? Do you think that you couldtell the difference between two people whose IQ scores differ by 10points? By 20? (Assume normal, everyday type conversations.) Atwhat size gap do you think there WOULD be a noticeable difference?What behavior(s) or other observations would signal to you that aperson has a higher IQ score?
