Final answer:
An IQ score of 105 is considered above average for a 13-year-old, placing them in the approximately 63rd percentile. This means they score higher than about 63% of their peers. However, IQ is just one measure of cognitive ability and does not account for other important aspects of overall success.
Explanation:
An IQ score of 105 is considered above average for a 13-year-old, or indeed for individuals of any age, as this score is slightly above the mean average of 100. IQ scores are designed to have a mean of 100 and a standard deviation of 15, so a score of 105 is within one standard deviation above the mean. This places the individual in the approximately 63rd percentile, meaning they scored higher than about 63% of their peers.
Most people's IQ scores fall between 85 and 115, which encompasses about 68% of the population according to the principles of the bell curve, and is generally classified as the 'average' range.
It's also important to understand that an IQ score is just one measure of cognitive ability and doesn't take into account aspects such as creativity, interpersonal skills, physical skills, and character traits like resilience and empathy, which are also important for overall success in life.
