Question

Accepted Answer

IQ, or Intelligence Quotient, is a measure used to assess human intelligence. The range of IQ scores is typically divided into categories to describe different levels of cognitive ability. The range of 90-110 is widely recognized as representing "Average" intelligence. Here's why Option 2 is the correct answer:

1. **Explanation for Option 2 (Average):**
   - The IQ range of 90-110 is considered to be within one standard deviation of the mean IQ score, which is typically set at 100. This means that individuals with IQ scores in this range are statistically average in terms of cognitive abilities.
   - The majority of the population falls within this range, making it the most common category. It represents typical intellectual functioning and the ability to perform everyday tasks without significant difficulty.

2. **Explanation for why other options are incorrect:**
   - **Option 1 (Very superior):** This category typically refers to IQ scores significantly higher than the average, often above 130. Individuals in this range are considered to have exceptional cognitive abilities, far beyond the average range of 90-110.
   - **Option 3 (Dull):** This term is sometimes used to describe IQ scores below the average range, often between 70-85. It indicates below-average cognitive abilities, which is not applicable to the 90-110 range.
   - **Option 4 (Fool):** This is not a recognized category in standard IQ classification systems. It is an informal and derogatory term that does not correspond to any specific IQ range. Therefore, it is not applicable to the 90-110 range.

In conclusion, the IQ range of 90-110 is best described as "Average," which is why Option 2 is the correct answer. This range encompasses the majority of the population and indicates typical intellectual functioning.
