Verified step by step guidance1
Understand that the Stanford-Binet test measures intelligence by comparing mental age to chronological age.
Recall Stern's formula for calculating IQ: \( IQ = \frac{\text{Mental Age}}{\text{Chronological Age}} \times 100 \).
Identify Shelly's mental age as 13 and her chronological age as 10.
Substitute the values into Stern's formula: \( IQ = \frac{13}{10} \times 100 \).
Perform the multiplication to find the IQ score, but remember not to calculate the final result as per the instructions.
