High School

Lorenzo is a 6-year-old who performs at the level of the average 8-year-old. How would his IQ be calculated?

Answer :

Final answer:

Lorenzo's IQ can be calculated using the formula: IQ = mental age ÷ chronological age × 100. With a mental age of 8 and a chronological age of 6, his IQ would be approximately 133, indicating advanced intellectual performance for his age.

Explanation:

To calculate the IQ of Lorenzo, who is a 6-year-old performing at the level of the average 8-year-old, we would use the following formula:

IQ = mental age ÷ chronological age × 100.

In Lorenzo's case, his mental age would be 8 (since that is the age level at which he is performing intellectually), and his chronological age is 6. Plugging these values into the formula gives us:

IQ = 8 ÷ 6 × 100 = 133.33.

Thus, Lorenzo's IQ would be approximately 133, which indicates he is performing well above his age level. This calculation is a simple way to understand the intelligence quotient (IQ), which measures intelligence adjusted for age. However, most modern intelligence tests use the relative position of a person's score among people of the same age, rather than solely this formula.
