Answer :
If the average 8-year-old answers 45 items correctly on a test, all individuals who get 45 items correct would be assigned the same A) Mental age.
Mental age is a concept used in intelligence testing, indicating the age at which a person is performing intellectually. To calculate a person's mental age, psychologists compare their performance to the average performance of individuals at different ages.
In this case, since the average 8-year-old scores 45 items correctly, anyone who also gets 45 items correct regardless of their actual age would be said to have the mental age of an 8-year-old.
