Quizplus · Accepted Answer

An IQ score of 105 falls within the normal range of intelligence, meaning that the person has an average level of cognitive ability. It does not indicate superiority or inferiority, and it also does not mean that the person scored higher or lower than 50% of those who took the test. IQ scores are normalized, meaning that the average score is set to 100, and there is a standard deviation of 15 points. Therefore, a score of 105 is one standard deviation above the mean.
