Quizplus · Accepted Answer

Generally, IQ scores are considered to be relatively stable throughout an individual's lifetime, so it is likely that Coleman's current IQ score would be similar to his previous score of 110. It is unlikely that his score would double or be cut in half, as suggested by options A and B. Option D is incorrect because although IQ scores are not perfect measures, they are generally considered to be reliable indicators of cognitive ability.
