Intelligence Tests (IQ)
Asked 2 months ago · Viewed 26 times
In the context of the modern formula (MA/CA × 100) used for calculating 'Intelligence Quotient' (IQ) in the Stanford-Binet Intelligence Scale revised by Lewis Terman, if a 10-year-old child (Chronological Age) has a Mental Age of 12.5 years, what will be their exact IQ level and under which intelligence category will they fall according to Terman's classification?
✓ Correct! Well done.
✗ Not quite — the correct answer is highlighted above.
Detailed Explanation
Lewis Terman has made a significant contribution to operationalizing the concept of IQ. The Stanford-Binet scale provides the formula of dividing Mental Age by Chronological Age and multiplying by 100. Here MA = 12.5 and CA = 10, thus obtaining (12.5 / 10) × 100 = 125. According to Terman's intelligence classification, an IQ level between 120-140 is considered 'Very Superior' or close to gifted.

In the historical and psychological development of intelligence, tracing from Alfred Binet's tests to the modern Intelligence Quotient (IQ), William Stern proposed the concept of 'Mental Age' and 'Chronological Age' ratio in 1912. Later, Lewis Terman in 1916 modified this in the Stanford-Binet Scale by multiplying it by 100 to establish the modern IQ formula. Based on this, if a child with a chronological age of 10 years has a measured mental age of 12.5 years, what will be the child's actual IQ value according to Terman's modified formula, and under which intellectual category does this score fall statistically?
