An 8-year-old child who scored like an average 10-year-old on an intelligence test would have a mental age of 10 and <span>iq of 125
IQ = </span>mental age<span> ÷ Physical </span>age<span> × 100</span><span>
In this case,
Mental age= 10
Physical age= 8
So, the iq calculation is:
IQ = 10/8 x 100
IQ = 1.25 x 100
IQ = 125</span>
