An 11-year-old child’s mental age is 13. Identify the descriptive level of IQ range for this child:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → High Average
IQ is mental age divided by chronological age, and multiplied by 100:
IQ = (MA ÷ CA) × 100
IQ = (13 ÷ 11) × 100 = 118.2, that is, about 118
On the classification of people on the basis of IQ, the range 110–119 is ‘High average’, so an IQ of about 118 falls in this band.
Option (1) Average covers IQ 90–109, Option (2) Superior covers 120–130 and Option (4) Borderline covers 70–79; an IQ of 118 is in none of these.

IQ refers to mental age divided by chronological age, and multiplied by 100.…” “…The mean IQ score in a population is 100. People with IQ scores in the range of 90–110 have normal intelligence. Those with IQ below 70 are suspected to have ‘intellectual disability’, while persons with IQ above 130 are considered to have exceptional talents. The IQ score of a person can be interpreted by referring to Table 1.1.…”
