Detailed explanation-1: -Stanford-Binet Intelligence Scale It remains a popular assessment tool today, despite going through a number of revisions over the years since its inception. The IQ score was calculated by dividing the test taker’s mental age by their chronological age, then multiplying this number by 100.
Detailed explanation-2: -The IQ was originally computed as the ratio of a person’s mental age to his chronological (physical) age, multiplied by 100. Thus, if a child of 10 had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), then the child was assigned an IQ of (12/10) X 100, or 120.
Detailed explanation-3: -Unlike the other tests, the Fagan test is correlated with measures of IQ in older children (habituation and dishabituation in infancy predicts intelligence in childhood and adolescence-quicker habituation and greater amounts of looking in dishabituation reflect more efficient processing).
