Final answer:
On an IQ test with a mean of 100 and a standard deviation of 15, a score of 130 and above is classified as Superior. This indicates a higher aptitude for learning and places the individual within the top 2% of the population.
Step-by-step explanation:
On an IQ test with a mean of 100 and a standard deviation of 15, a score of 130 and above is classified as Superior. This is because on modern IQ tests, an IQ score of 130 is considered to be within the top 2% of the population, indicating a higher aptitude for learning. People within this range may be considered 'gifted', especially within educational systems.
The classification system for IQ scores follows a bell curve, whereby 68% of the population scores between 85 and 115, which is one standard deviation above and below the mean and is considered average. Scores that are two standard deviations above the mean, such as a score of 130, fall into the superior category.
In the context of Mensa, an organization for highly intelligent individuals, a score in the top 2 percent of IQ scores is required for membership, which corresponds to the Superior classification.
