Question

Quizplus · Accepted Answer

While the average IQ score for each age group is indeed set at 100 and the distribution of IQ scores approximates a bell-shaped curve, it is not accurate to say that two-thirds of all IQ test-takers score between 95 and 105. In fact, the percentage of test-takers who score within a particular range depends on the specific test being taken and the population being tested. However, it is true that very high or very low IQ scores are rare.
