Question

Eight-year-old Terry's performance on an intelligence test is at a level characteristic of an average 5-year-old. In other words, Terry was average for his age group. Which of the following is most likely Terry’s IQ score?
a. 6
b. 4
c. 5
d. 8

Answer 1

Answer:

The correct option is C

Explanation:

If say a child is 8 years has an IQ score that is the same with the score of an average 10 years old child, the mental score of that child is 10. From our example, if Terry who is 5 years performs as an average 5-year old child, then his mental score is 5. However the IQ Score will be

5/5 * 100 (Since 100 is the average IQ Score) = 100
