Answer :
Amanda is said to have an IQ of 125.
The Stanford-Binet intelligence scale is a standardized test used to measure cognitive abilities in people. It consists of a series of tasks to assess verbal and nonverbal abilities, like language skills and problem-solving. The test is typically administered by a trained professional and is scored based on the individual's age and performance on the tasks.
An individual's intelligence quotient (IQ) is a measure of their relative intelligence compared to their peers. It is calculated by dividing their mental age by their chronological age and multiplying the result by 100.
Now, Amanda is 8 years old, with the proficiency of an average 10-year-old. Thus, the IQ will be calculated as -
(10 / 8) x 100
= 1000/8
= 125
