Suppose someone devises a new IQ test and we discover that tall people get higher test scores than short people do. What, if anything, should we do to determine whether or not this test is biased against short people? A. Interview short people who took the test to see if they felt the test was biased against them. B. Statistically analyze the results to see if, in fact, the two groups did get different scores. C. Look at school performances to see if the test accurately predicts performances of both short and tall people. D. Nothing else needs to be done: The mere fact that the test reports a difference between short and tall people is evidence of test bias.
