High School

Joe, a 15-year-old boy, performs about as well on an intelligence test as an average six-year-old. His IQ is about:

A. 25
B. 40
C. 60
D. 90

Answer :

Final answer:

Option b)

Joe's IQ score would likely be around 40, based on the proportion of his performance on the intelligence test in relation to his chronological age

Explanation:

Joe's IQ can be determined based on the standard assumption about IQ scores and mental age. Intelligence Quotient (IQ) is derived from the mental age divided by the chronological age multiplied by 100. In this case, Joe's mental age (6 years according to his performance on the intelligence test) divided by his chronological age (15 years) multiplied by 100 would give us approximately 40. Therefore, Joe's IQ would be around 40.

It's important to note that having an IQ of 40 typically indicates a severe intellectual disability. A person with an IQ of this level usually struggles with basic cognitive functions and lacks the necessary skills for independent living. However, a variety of other factors also play a role in determining a person's ability to function in society, and an IQ test is not the only measure of a person's mental capacity or potential.
