Imagine a 5-year-old has the mental age (MA) of an 8-year-old. What would their IQ be according to William Stern's IQ score?

A. 100
B. Above 100
C. Below 100

Answer :

The IQ would be B) above 100 based on this calculation

To determine the IQ, we can use William Stern's formula: IQ = (mental age / chronological age) × 100. In this case, the 5-year-old child has a mental age of 8.

1. Mental Age (MA) = 8
2. Chronological Age (CA) = 5

  • Using the formula: IQ = (8 / 5) × 100 = 1.6 × 100 = 160

Therefore, the IQ would be above 100 based on this calculation.
