Question

Quizplus · Accepted Answer

IQ scores are standardized, with an average score of 100 and a standard deviation of 15. This means that the majority of people will score within one standard deviation of the mean (85-115). Therefore, there will be more people scoring near 100 and fewer people scoring farther away from it. Options A and D are incorrect as IQ scores do not have an equal distribution of scores within a specific range, and option C is inaccurate as dividing an IQ score by 2 does not give the percentile rank on the intelligence test.
