Answer :
Final answer:
Chelsea's IQ of 110 obtained from the Stanford-Binet test translates to a Mental Age of 11 years old, due to the inherent formula used in IQ testing.
Explanation:
The IQ or Intelligence Quotient is usually determined by the formula: IQ = (Mental Age/Chronological Age) x 100. This formula plays a fundamental part in the Stanford-Binet IQ test. In Chelsea's case, her Chronological Age is 10 and she scored an IQ of 110. We can rearrange the formula to solve for Mental Age which gives us: Mental Age = (IQ x Chronological Age) / 100. Substituting her values we get : Mental Age = (110 x 10) / 100 = 11 years. So, considering Chelsea's IQ score, her Mental Age according to the Stanford-Binet IQ test would therefore be 11 years old (option C).
